You might be a fan of Hubski then - it's a pretty similar interface to Reddit, but in addition to a global top (i.e. frontpage) and tags (i.e. subreddits), you can follow other users and get a feed of the content they like. It's a pretty elegant approach, and helps you see a good range of content if you follow accordingly.

It's also a much better userbase to my mind, but that's probably a function of small size.
