Today Facebook surpassed the 500m user mark and is the most visited site on the internet but it’s not quite time to celebrate.

This is all at a time when pretty much every platform is integrating Facebook in some way as it seems to be the social network. So the simple question: how much do you love/hate Facebook and is Facebook integration something you require in a phone?
