Favorite Facebook Apps

Being somewhat new to Facebook, I am still enjoying my time on there. I am curious as to which Facebook applications you are all using, and which ones are your favorites.

I really like checking the pictures available in the Bumper Sticker application. Most of them are ridiculous, and some are offensive, but I usually find at least one or two really good ones on the first handful of pages. I also like using the Flixster Facebook app, and really like taking some of the quizzes. For quizzes, though, I like the iLike application even better. Being the music junkie that I am, iLike is a perfect application for me. The music quizzes are usually insanely difficult, but they are a blast to play.

What are your favorite Facebook apps? What do you find yourself doing to kill time while you’re logged on over there?
