The problem I experience with Mastodon is it seems like a total echo chamber. Very little interesting conversation most of the time. I still find good links to content there though.
It's no surprise that can end up feeling like an echo chamber. It's getting better than it was when I first started using it about six months ago but some of the posts people catch heat for seem a bit too over the top.
One of my favorite examples was a user who posted a photo of their dinner. It was nothing crazy just like rice, veggies, and chicken. They were immediately accosted for not posting a trigger warning since some people have eating disorders. That's the type of community I have no patience for.
