microblogging is something used on a much more personal level while i think forum style social media is mostly for looking for answers and posting things you do, but microblogging social media sites are for that too. also, this is not meant to be offensive, but i think that since mastodon has been in the works for like a long time, it looks more polished than modern websites, so that can be an advantage it has
I personally don’t value the microblogging format and never really gave it a shot. It’s just personal preference. In my opinion, the site format mechanically encourages low-effort junk, and there’s enough of that on sites like this. I only use microblogs as an inconvenient feed for specific niche news updates I can’t get elsewhere, like I would an RSS-type feed.
With that said, I support people posting on fediverse microblogging sites rather than on xitter or bluesky. I have to jump through a lot of moving hoops to even view xitter feeds without an account.
