Twitter updates

Today I have updated my twitter page.  I set up a background and a few lists.  I think it came out ok.  So far I don't see what the big deal is with twitter.  It doesn't seem to be that informational, more like just a way to keep track of complaints.  Either way, I have finished getting it set up and am going on to see what else it is good for.  How has everyone else in Web 2.0 been doing with this so far?????
