I have to admit, while I like the idea of Facebook having real competition, I'm not sure I want Google to be the one taking them down. They're getting about as monolithic as Microsoft ever was.
What's worse is that Google is flat out abusive with privacy and personal information. Facebook is known for turning over information to government agencies, but Google blows Facebook out of the water when it comes to infringing on personal information.
