Facebook - Fun times for how long?

Tweet

I have noticed that the magnitude of applications on facebook are more than entertaining for a short time, but grow dull very quickly and are soon replaced by a new fun application that follows suit. Do you also feel this way? Have you found an application that stays fun and entertaining through the long run? All the applications I have come across were crazy awesome but are now a quick check once a day and I'm done. Comment, suggest, retort, etc. Thank you.
