Interesting comment on the article:

Makes more sense for Google to buy them. They could do two things with them:

1: build the technology into their Google Glasses so peoples names pop up as they come into view 2: redirect face.com to Google.com.

That second option would be well worth the 100 million too. Consider this: after you visited face.com once every next time you want to go to facebook.com and type in 'face' your browser will auto-complete to face.com

1 and 2 are both interesting scenarios.
