I'm up to 92 so far. A mix of non English, furry and hentai porn, and a few I just don't see the point of. I've got 6 or 7 users to, mostly bots that repost reddit content, and the piped link bot.
102 so far. It's mostly porn and the creepy hentai and furry stuff, some of the foreign language communities that get through the filters, and things like different sports, that I'm never going to be interested in.
As other people have said, I want to be able to browse through All to discover new content, but there's no point in seeing things that I'm never going to like.
