I unfollowed everyone on facebook because it's mostly just pointless or political crap that I couldn't care less about or I would piss people off by responding with devil's advocate tendencies. comments on posts are just as bad mixed with horrible filtering of "top comments". Reddit though feels much more useful on specific topics and hell I don't even have a reddit account, but a lot of times if I am looking up a subject or troubleshooting something I usually will click on reddit posts that come up in search first because usually comments are more useful, at least more useful than anything I ever saw on facebook.
