This site moves REALLY slowly. There's not millions of users like on reddit. It's not unusual for people to see and comment on several day old content.

And the breadth of content is certainly lacking as well, this is due to a user-centric focus, which means the people who find content they like here are going to simply add to 'the problem' of not having breadth.

If there's not many philosophy posts, that means the current users don't particularly post about philosophy that often. Perhaps you can kickstart that?

Follow some good users that you like, and see what they share. It's a different model than reddit.

Do keep in mind that there's lots of redditors coming over at the moment, which means a lot of the discussion is going to be about how hubski is different. It should clear up in a few days. I personally find that most of the content here is long-form articles, about a variety of "real-world" topics.

If you want a "subreddit for everything' kind of place, you've really stumbled into the wrong part of the internet. It'll get there.... eventually.
