There is more to facebook than poking
I just added the Jobster facebook application and this great image had me laughing.

It shows how businesses are finding ways of providing value in facebook other than entertainment. However, then I noticed that they only had 110 active daily users! The reason = they don’t provide much of a reason to return to their application. Job alerts are emailed, and most of the links take you out of facebook. So I don’t really consider it a true facebook application.
