Since the platform launch, I've added what seems like 80 bazillion applications to my profile. I only use 2 of them on a regular basis, and these have become my favorites :
So I was thinking, you know what'd be sweet, is if some of these apps were made available for mobile phones. Not all of them, because the facebook mobile site is just perfect the way it is now, and I don't want the page to get too cluttered. But I can totally see the need for applications beyond the basic Facebook set to be available through a cellphone. Like the Hangouts application. I could totally see myself using that on my cell phone.
