Why do I need an app? Because I like to keep up and keep in touch with people that I'm friends with on fb. And because the mobile sites suck.
Bloo delivers notifications shortly after they hit the system in a convenient way and makes viewing people's profiles and ESPECIALLY pictures a whole hell of a lot better.
I totally understand this topic here. If you were a blackberry user before the droid and an avid facebook user, the blackberry wins. Motorola has Blur but it is not going to be on the droid unless someone can port it over somehow. Supposedly in the training I took yesterday on the Moto Devour you should get them instantly as the BB would. Gosh I miss instant notification. Bloo has nothing on it.
I don't know what you guys are upset about. The Facebook app notifies me with every new mail message. The only real thing that stinks is the lack of a mailbox and the fact that several functions are really just using the mobile entry to the Facebook site. Otherwise I don't miss too much.
