I think Facebook has way better engineers than AOL did, though, and an extremely engineering-oriented culture. The infrastructure they've built up already is also very valuable; only a small handful of companies can match them there. I think those two factors will be their saving grace. Even if FB as a social networking website never becomes highly profitable, their talent and infrastructure should let them easily pivot into other areas and remain relevant. I would never bet against a company that has a few thousand of the best engineers in the industry, and ambitious management.
