Facebook does not want Google on their side at all, just look at their robots.txt

Those are pretty sensible exclusions, preventing the indexing of search pages, duplicate content, and so on. Google reports over 5.6 billion results from FB in its index.

This is good news for FB if if encourages wider adoption of its comment system.
