Totally agree
I mean, what is facebook? Microbloggin + groups
Personally what I'd like to see if something that Approaches Myspace or Tumblr, with personal homepages and music sharing, ya know, *fun* stuff that allows people to express their individuality and find and share media they enjoy, but also full integration into forums. We're not really that far off, Kbin is pretty close, tho i think the "reddit clone" is a similar dead end to a "twitter clone" . . . reddit is just forums, there are a million ways to do forums it doesn't have to look like reddit
