I'd be intrested to learn more about BlueSky but as far as I know you still have to be invited to join it :(

Yeah, unfortunately.
And frankly? Not a huge fan of it.
Seems like a more desolate version of Twitter with LESS features as of right now, and while a lack of ads is nice, I've been, though my own observation, enjoying the community and form factor of Cohost a lot more.

I mean it is a new website, I understand why they're doing what they're doing. If they opened it up fully from the get go. Then it'd be like mass DDOS with the influx of users, as for the lack of features those will be rolled out as they expand their team and such.

Yeah, I'd like to believe that, but they've been founded for nearly 2 years at this point, and are still only in a semi-open beta at this point.
Cohost, in comparison, to quote their own website, "launched in private alpha on february 3, 2022, and to the public on june 28, 2022."
That's a massively shorter timespan for full public release, and anyone can just make an account for it nowadays, with only a 2-3 day waiting period before you're allowed to post (at least, when I joined a couple months ago).

Just... I get what the Bluesky team's trying to do, but I feel like they're being too safe/conservative about it at this point.
Plus, Cohost has some pretty damn crazy shit it can do with CSS markup and HTML if you're savvy enough. You can basically program your own custom post format.

I dunno. I'll probably use them both, but if one fully replaced Twitter, I think it's safe to say you know what my money's on.

Giving a follow!

If Twitter gives me any more problems, I might consider Blue Sky.
