What are some websites that you check on a daily basis and why?

Mine are http://Flurther.com – because always find out something interesting, http://Twitter.com – to update, http://Livejournal.com – to read my friends and community posts, http://Myspace.com – to update my friends about what we’re doing this weekend and check messages,etc, and my Google Reader to find out everything else! What about you guys?
