Twitter.  Everyones on it now.  I can use it to hear from a newly reformed band such as Blink 182 (Mark Hopus) post pictures from only moments ago of their current happenings in their lives.  I can get P. Diddy's insights into daily life, and my personal favorite, police information on what's going on around Boston (other police forces are beginning to do it as well).  Twitter is getting big.  Real big, real fast.  Early reports indicate twitter doubling in size in the past month, CRAZY.

Who knows what the future will hold for twitter, however it's growth is far stronger than facebook's was at this time in it's life.  Watch out for it.  If you don't have one and want to stay in the know, get one.  Now.  The End.
