reddit is almost entirely in existence due to its community/userbase. it's all it had when digg imploded, and it's pulled them through from dark to the traffic heights they are at now.

thing missing from reddit, despite the forum-like discussion thread part, is that it isn't social. it doesn't promote following users or anything of that nature or has little of those features (one thing that digg has/had)

thing is, currently, the way reddit is/is going -- there's not much that needs to be changed. it covers alot of use cases for alot of its userbase (i.e. I use it solely for submission and upvoting/link popularity tracking, and hardly for anything discussion/forum related)
