I registered for the 23 things program several weeks ago and I'm just now making my first post! (Guess which of the lifelong learning habits is my weak one...)
Some of the "things" I'm already familiar with and some I'm not. Sharing funny Youtube videos is a weekly ritual for my friends and I, and Wikipedia is often my first choice for finding information online (shameful for a librarian, I know). On the other hand, I've never heard of odeo or bloglines, so that'll be all new.
Let the learning of fun begin!
