If I was Facebook, I'd start downsizing my company to a slim and trim archival service, maybe even start charging a fee for executive functionality (like what? I dunno) to help support server costs. Maybe even go distributed content where everyone hosts (encrypted) content and shares bandwidth. IMHO online social networks have a 5-7 year half life, after that they stagnate and die because the company tries to chase ad dollars (the easiest dollars to get) and step by step degrades their usefulness. For some reason we don't model business on natural systems (birth -> growth -> reproduction -> death). Seems to me that'd be a good idea if we want to be around in a million years.
