This is a decent app, but not one I use often despite being on Facebook regularly. It just doesn't provide anywhere near the same level of functionality as actually using a web browser.
Who doesn't wanna know when someone writes on their wall or pokes them? I know I do. the feeling of joy just knowing that someone cares enough to leave you a comment. Oh wait, what was that? Someone from high school just found me? OMG I haven't seen that person in 10 years, I'm so excited. You get my drift.
