The more I think about this, the less I lump Google and Facebook together when I talk about privacy. Maybe it's just because I don't use Facebook all that much, but I don't consider them to be exactly equal, and suggesting that everyone not use both at the same time no longer works for me. I don't disagree with some or even much of what's on this site, but Google has built some amazing things that are widely used. I can't think of much to say about Facebook in that way. Google has mail and docs and maps and all the chat things and analytics and so on. Really powerful impressive things that are really useful to many people, and certainly useful for Google in obvious ways. Facebook has... Facebook. Maybe I'm missing other things that it does?
