i have the same issue on tumblr where i follow 781 people and it's a problem because ill go to an art blog, follow the blog for the art, and then never see it because it's caught up in all the other posts and i forget the urls.
ive started unfollowing blogs that are people who post a lot of personal problems or sj stuff. not that i don't care, but i really just need to chill out more and enjoy art n stuff rather than getting angry about stuff i cant do anything about.
