Nostr seems marginally better than X for technical & cypherpunk content.
The culture is significantly more cringe though and that's saying something.
Discussion
Significantly better for technical content, but there's less of it. The bitcoin-dev mailinglist and Delving forum have much more content, and for the time being are better platforms imo.
Delving daily email summary & Google groups bitcoin dev daily summary are definitely the best.
Cringe? More raw and unfiltered imo
