tpot

1."This part of Twitter": the loose constellation of postrat, tech-adjacent mutuals who share memes, meditation takes, and contrarian threads. There is no membership list, and if you think you're in it, you are not actually in it. Hope that helps.

He insists he's not in tpot, which is the single most tpot sentence a person can produce.

01Origin

The cluster formed around the COVID lockdown out of the "postrat" (post-rationalist) diaspora: people who had passed through the Rationalist and Effective Altruism movements and came out the other side interested in vibes, spirituality, and posting. "This part of Twitter" was the only name vague enough to survive, precisely because the community is not an organization but a mesh of mutuals; no coiner is attributed.

By the mid-2020s tpot had become a real SF-adjacent social scene with meetups, group houses, and festivals, covered by everyone from LessWrong ("Explaining the Twitter Postrat Scene") to Know Your Meme, which files it as a subculture. It survived the platform's rename to X, various discourse cycles, and a partial migration to Bluesky, none of which produced a better name.

The definitional joke is load-bearing: since "this part" is indexical, every reader stands somewhere different, and the timeline periodically relitigates whether tpot means this part or that part of Twitter. It is the rare SF-ism that names a place with no coordinates, unlike Peter Thiel's hot tub, which has coordinates nobody will give you. Declaring things anti signal is a popular tpot pastime.
