Social Media Networks for Physicians: Doximity, Sermo, Figure 1 and What Comes Next
Every few years someone announces the LinkedIn of medicine, the Facebook of medicine, or the Twitter of medicine. Most of them die. A few survive because they do one specific thing well and stop pretending to be everything else. If you are deciding where to spend your limited attention, you should know what each network actually delivers, not what its marketing page claims. I have used all of these. Here is the honest version.
One housekeeping note before we start: Doximity, Sermo, Figure 1, Student Doctor Network, Reddit and every other product named here are trademarks of their respective owners. This site has no affiliation with any of them. This is one attending's opinion, nothing more.
Doximity: the directory that became infrastructure
Doximity's core asset is boring and valuable: a verified directory of United States physicians tied to real identities and NPI data. That directory powers the two features most physicians actually use.
The first is the dialer. You can call a patient from your personal cell phone and have the call display your office number. If you have ever taken call from home and hesitated before dialing a patient back, you understand immediately why this matters. It is the single most used feature in the entire physician social media landscape, and it has nothing to do with being social.
The second is the fax and document workflow. Electronic faxing sounds like a punchline until you need to send records somewhere at 9 pm. It works.
What Doximity is not, in practice, is a place where physicians talk to each other. There is a news feed, there are comment sections, and there is engagement, but the feed is largely aggregated headlines with commentary layered on top. The residency navigator and salary survey data are genuinely useful for trainees comparing programs, and worth a look during interview season. But if you arrive looking for the hallway conversation of medicine, the back and forth where someone talks you through a hard case, you will not find it there. Doximity is infrastructure. Use it as infrastructure.
Sermo: anonymous peer discussion, with a business model attached
Sermo took the opposite bet: physicians will say what they actually think only when their name is not attached. Verified physicians post under pseudonyms, and the discussion quality reflects that freedom. People admit uncertainty. People describe complications. People ask the questions they would never ask in front of their department chair. That candor is real and it is the platform's genuine strength.
The trade-off is the business model. Sermo makes significant revenue from paid surveys and market research, and the experience reflects it. Survey invitations are constant. Some physicians treat this as a feature, and honestly, filling out surveys during a slow call night is a legitimate way to pay for a vacation. But it shapes the platform. You are the product being studied, and the discussion forum sits alongside the survey machine, not above it.
The anonymity cuts both ways too. It frees honest discussion, and it also frees the other thing anonymity frees. Threads on anything politically adjacent can get ugly in ways that a named community rarely does.
Figure 1: the case image library
Figure 1 built its identity around one sharp idea: clinical images, shared securely, with identifying information stripped out. At its best it functions like the world's largest teaching file. A resident in a community program can see the rash, the ECG, the radiograph that they would otherwise only encounter in a textbook or by luck. The consent and de-identification workflow was thought through seriously, which matters, because posting clinical images carelessly is how physicians end up in front of a licensing board. If you ever share cases anywhere, strip every identifier and follow your institution's policy, full stop.
The limitation is that a case image platform has a ceiling. You look, you learn something, you leave. It is a reference and a teaching tool more than a community. Sustained discussion, mentorship, career talk, the connective tissue of a professional network, was never really the point.
SDN and Reddit: free, open, and exactly what that implies
Student Doctor Network has been running forums since before most current residents had email addresses. For premeds and medical students it remains a deep archive: application timelines, school-specific threads, years of accumulated answers to every version of the question you are about to ask. The archive is the asset. The culture is the liability. SDN's reputation for neurotic score-comparing and casual cruelty is earned, and you should read it the way you read any anonymous forum, with a thick filter.
Reddit's medicine communities are, in my opinion, currently the best free discussion spaces in this entire landscape. The residency and medicine subreddits have real talk about programs, contracts, burnout, and clinical practice that you will not find on any verified platform. The problem is structural: anyone can claim to be anyone. The confident voice explaining ICU ventilator management may be an intensivist or may be a first year pharmacy student. Verification does not exist, moderation varies, and you can never fully trust that the room contains who it claims to contain.
What each network actually gets you
| Platform | Best at | Weakest at | Verification |
|---|---|---|---|
| Doximity | Dialer, faxing, directory, career data | Genuine peer discussion | Verified identity |
| Sermo | Anonymous candid discussion, paid surveys | Signal to noise, survey fatigue | Verified, pseudonymous |
| Figure 1 | De-identified case images and teaching | Ongoing community and discussion | Verified |
| SDN | Application archives for students | Culture, tone, anxiety spiral | None |
| Unfiltered discussion, breadth | Knowing who you are talking to | None |
The gap nobody has filled
Line those platforms up and a gap becomes obvious. The verified platforms are not built for conversation. The conversational platforms are not verified. What most physicians actually want is the hospital cafeteria table: a room where everyone is actually a clinician, where you can ask a curbside question without performing for an audience, and where nobody is primarily there to sell you survey participation or ad impressions.
That gap is the reason we are building CurbSide, the free community attached to this site. I will be straight with you about what it is, because overclaiming is what every failed medical network did on day one. CurbSide is new. It is in its founding phase. Physician members are NPI-verified, which means when someone answers your question, you know a real clinician wrote it. The CurbSide feed is where those conversations live, and joining costs nothing. What it does not have yet is a decade of archives or a massive user base, and I am not going to pretend otherwise. What it has is the correct architecture: verification plus conversation, which is exactly the combination the incumbents never managed in one product.
How to actually use these platforms as a trainee
If you are a student or resident, here is the practical allocation of your attention.
- Get Doximity for the dialer. The first time you return a patient call from your couch without exposing your cell number, it pays for the five minutes of setup. Look at the salary and program data during application season, then close the app.
- Read Reddit, but calibrate. Treat it as a source of questions worth asking, not answers worth trusting. When a thread tells you something clinical, verify it against a real reference before it touches a patient.
- Use SDN as an archive, not a home. Search it. Do not live in it. The anxiety is contagious.
- Try Sermo if anonymous discussion appeals to you, and go in knowing the survey economy is part of the deal.
- Join communities early when they align with how you work. Small verified communities are where you can actually be known, which is the thing large platforms structurally cannot offer.
And keep your time budget honest. Social platforms of every kind are engineered to consume attention, and your attention is the scarcest resource you have in training. Thirty focused minutes reading a good discussion of a case you just managed is education. Two hours of scrolling is not. If your time is going to a screen, it should compete with the other things that make you better, like drilling the skill of presenting a patient on rounds or working through the rotation guides and practice questions on this site.
The rules that apply everywhere
Whatever platform you use, the professional rules do not change, and pleading ignorance has never once saved a physician in front of a board.
- No patient is ever identifiable. Not by name, not by date, not by the combination of rare diagnosis plus small town plus timeline. If a patient could recognize themselves in your post, you have already crossed the line.
- Anonymity is not protection. Pseudonymous accounts get unmasked. Write every post as if your name, your program director, and your state board will read it, because eventually one of them might.
- Do not give patient-specific advice to strangers. Discussing medicine in general terms is education. Telling an anonymous person what to do about their chest pain is practicing medicine on someone you have never examined.
- Disclose conflicts. If you are paid by a company whose product you are praising, say so. This is not optional.
Local policy and your institution's social media rules govern, and they are usually stricter than the platform's terms of service.
Where this is heading
The consolidation has already happened once. A decade ago there were dozens of physician networks. Now there are a handful of survivors, each holding one defensible position: Doximity holds identity and workflow, Sermo holds anonymous discussion, Figure 1 holds images, and the open forums hold everything too messy for a verified platform. The next round will be decided by the same question that decided the last one: does the platform give a working physician something worth five minutes of a day that has no spare minutes in it?
Where HistoryandPhysical.net fits in
Since the article is about where physicians gather online, it is fair to say what runs here and who it is for.
- A forum open to everyone. The community requires no NPI and no credential check, because anyone interested in medicine should be able to join a conversation about it.
- A separate network for licensed clinicians. CurbSide is its own app and does require a verified NPI, so the clinician only space is genuinely clinician only.
- No ads and no data sale. The site carries no advertising anywhere. Membership pays for it, which is the entire business model.
- Free tools alongside it. 33 rotation guides, calculators, note templates and the Evidence tool, which cites PubMed, Europe PMC and published guidelines.
Membership buys the question banks and exams only. Everything named above is free.
My honest advice is to own your professional identity on the infrastructure platforms, learn from the open forums without trusting them, and invest your actual participation somewhere small enough to know you and verified enough to trust. If you want to see what we are building toward that end, the community is free, verification is by NPI, and the door is open. And if you are still deciding whether any of this is worth your time, start with the rest of the blog and judge the quality of the thinking first. That is the correct order of operations for joining anything.
Fair is fair: this site belongs in the landscape it just reviewed, so here is the honest placement. Doximity, Sermo, and Figure 1 each win the thing they are built for, the directory, anonymous peer volume, and case images respectively, and nothing here replaces them. Use them for what they win at.
