This may not be exactly what you are looking for, but one thing that increased my enjoyment of reddit and twitter was making heavy use of lists and multireddits and unsubscribing from things I didn't want to see without looking for. For example, I was subbed to a half-dozen Diablo related subreddits that were more popular than some of the smaller subreddits I was interested in. This meant that my homepage was cluttered with posts from those subreddits. Therefore, I made a Diablo multireddit and ubsubbed from the Diablo related subreddits making my homeoage a bit cleaner and it has the added benefit of concentrating the Diablo information when I am looking for it. I also do this in an inverse manner. For example, I'm still subscribed to the team subreddits of sports teams I follow, but since they tend to be small, I have them lumped into a "My Teams" multireddit where I can easily check what is going on for the half-dozen teams I really care about. The use of multireddits has greatly improved my reddit experience.
