I just updated my Goodreads shelf from zero books to something around 50 books. I have also restarted a last.fm account, a del.icio.us account, a Twitter account, and a Flickr account. I am also working on a new blog template (as I always am) that will display all this information, because I hope that someday I will be able to aggregate myself to eternal life, kind of like Lawnmower Man (Jeff Fahey version). Like, what if I died, but set enough future Twitters, Flickr posts, Last.fm Scrobbles, AIM away messages, and new bookmarks to last for the next 20 years.
This is probably already the subject of 20 Wired pieces.
