What we would do without Twitter? If not for that 140 character service, I never would have found out that Dr. Chaotica wrote and performed a song called "Death from the Skies!", based on what is considered by some (OK, just me) to be the finest book to come out in 2008 (and 2009 in paperback). I'm more of an ABBA and Shostakovich guy, but I have to admit I found my toe tapping to this happy tune of death and destruction from space.
