the problem is convincing all of your family and friends to use it too, otherwise you'll be updating your page with stuff that no one will ever see.
it's basically a mobile oriented social networking app a la facebook or myspace, but like i said, highly specialized for mobile applications rather than a social site with a mobile app built as an afterthought.
if everyone you know is willing to bend to your will, try it.
the question is "what are you trying to get out of it?"
Well I think that you may have a little self importance issue if you need to update a page like that so many times a day. I mean I use myspace and facebook on my berry but a dedicated mobile social network? Dang!
