One of the many things that makes Bluesky deferent from most social media platforms (besides the whole open source thing) is the character limit, on Bluesky by default you get a max of 300 characters per post, if you need more you start a “threaded post” and while the character limit can be annoying some times is 300 characters enough why not 500 characters?
Threads and Mastodon both have a 500-character limit so why not Bluesky?
Bluesky is a microblogging platform, or at least that’s what Wikipedia says, so it doesn’t need the extra characters but sometimes you're going to run into “dang it, I’m 3 characters over the limit” so now you need to start a threaded post all because of those 3 extra characters.
Threads is still a microblogging platform but it ain’t Meta has introduced a new longer post feature so now it's more of a blog.
But I feel like the 300 character limit is just right, it’s at a nice even 300 and it isn’t too small that you need to constantly make threaded posts but more like an every so often thing.
