Most posts about #37c3 were published on the Fediverse.
I found 11.130 posts on the Fediverse (known to chaos.social or mastodon.social), 2.620 posts on X/Twitter and 1.069 on ATProto/Bluesky. Published between 2023-12-23 and 2023-12-31. (I haven't figured out how to collect posts on Threads, but I have found 150 there. Maybe there are more, but they don't show up in the search results.)
@luca Following #37c3 via Mastodon during congress felt just like in the olden Twitter days. I also don't see any other network having the momentum to change this any time soon. At least for this community, this seems settled.
