Skype for Windows 5.5 saw Facebook integration but now Mac-based users will get the same great feature. Skype 5.4 beta allows you to do things like chat with your Facebook friends, read and update your news feel and even "like" posts, all directly from Skype. It doesn't include a revamped or new-looking UI which means most people might stick to version 2.8 for now. For those who want to hit up some Facebook integration, grab Skype 5.4 beta!
