The Canadian government sent us a $750K cheque to build Stan in Toronto instead of moving to San Francisco. That is what SR&ED feels like when you actually claim it. The CRA pays you for building product in Canada, and the question of whether to relocate answers itself. We…

How we count
Postel's library follows thousands of individual creators on X: founders, builders, writers and other people posting as themselves. Brands, news and fan accounts, politicians and aggregators are kept out. This page reads their original English posts from Oct 26 – Nov 1, 2026, leaving out replies and reposts.
A post counts as viral when it gets at least 3 times its creator's usual views and 10,000 views in all. A creator's usual is the median views of their posts over the 60 days before the period ended, leaving out posts younger than three days. Comparing each post with its own creator means a big account's ordinary post doesn't count, and a small account's unusually big post does.
A model then reads every viral post, sorts it into a topic by what it's about, and leaves out politics, gossip, news about other people, health claims, get-rich pitches, giveaways and anything else this page shouldn't feature. A second, stricter model approves each post before it's shown with its creator's name. The list ranks the approved posts by how far each beat its creator's usual, one post per creator. Openings are sorted by the plain rules in the table.
Every post links to the original on X. Creators: if you'd rather your post weren't on this page, send its link through the contact form and it comes off within a few days.
