Well i prefer facebook but before the design change, yet facebook is better than myspace and for many many reasons .. i donno but myspace feels so cheap .. i donno why ... anyway i dont use any of them anymore ..
Facebook.
+ no to colour profiles.
It's so much easier with facebook, and there's no pages with horrible music playing out loud.. all pages take the same time to load... and the layout is very user friendly. Saying this I was totally against new facebook, now i'm loving it. It's great.. there's no longer applications EVERYWHERE!! :D it rules ++
For lots of reasons.
