Would facebook's data actually be useful to the NSA? I think they would get a lot more actionable data out of emails, SMSes, phone transcripts, accounting software, project management software, etc. The only thing I can imagine facebook being good for is perhaps knowing who they want to start looking at in the future. Search engine history might be more effective for that, though.

The point is, this data exists. The NSA has all of it. What are they doing with it? Probably nothing good.
