Facebook is trying to make itself more attractive to business users by, among other things, allowing users to segregate their business contacts from their strictly social ones. While this is useful it doesn't make Facebook a business tool. According to a new study from Flowing Data, just a few of Facebook's 23,000 plus applications are business-oriented. Nearly half of them are "just for fun" while the "gaming" and "sports" categories include more than 2,000 applications each.
