Saying the product of the kidneys is urine is like saying the product of a factory is pollution. Urine is a by-product. The product is homeostasis.

First question I asked them when they approached me. No way this can be a viable replacement for #MedTwitter without the world (and non-physician providers). They assured me it is on the road map. We'll see.

* yeah yeah yeah, I know that today only American physicians are welcome, but the leadership at Roon assures me that the roadmap includes expanding the community to both physicians in other countries and other medical professionals. For now, sign up for the wait list

• A place optimized for teaching, debate, and mutual support
• A place that values intellectual rigor more than pharmaceutical ad inventor

I’ve spoken with the founders. Their vision aligns with what many of us have been missing.

Just as Tikkun Olam calls us to actively repair the world, a platform still under construction gives us the chance, and the responsibility, to shape it into the professional community we want.

• A place built first for physicians talking to physicians

Which brings me to the newest kid on the block: Roon for Doctors. It’s so young it just qualified for its first DTaP vaccine.

And that’s the opportunity.

I like BlueSky but a year after NephJC moved to their from X the community remains stagnent. I think the original sin here is that Blue Sky emerged from resistance politics which makes it particularly distasteful to a lot of medicine. And for that reason it cannot be a viable MedTwitter replacement.

Threads had promise, but living inside Zuckerberg’s Orwellian panopticon made me long for something closer to an Enlightenment coffeehouse.

It really never achieved lift off with our people.

LinkedIn has recently seen increasing use by doctors, but the polished, corporate-Stepford energy makes real intellectual interaction…unlikely.

We have tried Mastadon, which has established itself as a viable destination for nerds, and nephrology would find itself at home is such a place, but we need to bring our less nerdy medical colleagues along to remake MedTwitter and they balked at the complexity.
February 17, 2026 at 6:37 PM
Right now, many of us are wandering through the post-#MedTwitter wilderness looking for the next place to rebuild what we lost — a space where nephrology and medicine can argue, teach, listen, and learn in public.

Sounds like you need a higher quality nephrologist
