Fediverse

When I tried it in the past, I kinda didn't take it seriously because everything was confined to its instance, but now, there's full-featured global search and proper federation everywhere? Wow, I thought I heard there were some technical obstacles making it very unlikely, but now it's just there and works great! I asked ChatGPT and it says this feature was added 5 years ago! Really? I'm not sure how I didn't notice this sooner. Was it really there for so long? With flairs showing original instance where video comes from and everything?
