I have never been on twitter so I don't really know but I can agree that we see tech community in twitter but the same isn't really there in bluesky.

Although I still have a web/programming which I follow and have found some people interesting from Hackernews and others too in bluesky (emsh,simonw)

What is the HN consensus around lemmy? I really like lemmy and think that it might be better for tech stuff (almost similar to HN/reddit you can say and federated)

I used to follow lemmy c/technology but I do feel like HN is pretty unique in its own manner.

Regarding twitter alternative itself. Maybe mastodon too can be an alternative.

Another minor nitpick about bluesky is that its 200 characters limits actually really removes the tech community from too deep discussions imo. Although I guess twitter had that limit for long time too until it got removed but now I do see sometimes some tweets which are really long (sometimes even complete blog?)

It actually really (pissed?) me off so much that I ended up making a tampermonkey script which can actually write a long message automatically and split a message into 200 messages chunk and post them in a thread of sorts you can say although its very hacky and messy and it starts to glitch around 10 threads from what I remember.

It's 300 characters. Have you considered writing it on leaflet.pub or something and linking it, if it's not a back and forth? There's already a + button in the post composer to split into multiple posts.

I think there's a few tweetlonger-type services that people have tried to make, but with atproto they can at least embed that extra text into the post (100kb limit), so the site only needs to stick around to view it.
