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
Micro-blogging sucks because it fosters a ‘community’ of people who are only there to gain popularity/followers.
Reddit/lemmy style social media is more focused on sharing interesting things and having discussions.
