I used to spend upwards of 2-3 hours a night going through all of my favorite blogs, reading and checking for updates.  While fun and entertaining, it was not exactly the most efficient use of my time.  I recently stumbled across the Google Reader and am in love.  I uploaded all of my blogs URLs and the reader checks them for updates so anytime I go to the reader, it shows me which blogs have new updates.  LOVE IT!  You definitely have to check it out!
