People have different tastes, which can vary.
Microblogging is something more casual, and has more focus on the people sharing content. Community foruns are revolved around the content shared, so you don’t really get to know people, so it has a difference on what they actually want.

Community-based platforms aren’t receiving as much attention because while Reddit is getting worse and worse, it has not reached the level of enshittification Twitter is at. Most people are still going to keep using it. Twitter on the other hand is reaching the point where huge amount of people are leaving, making alternative microblog platforms very relevant.
