thing is, internet is a fragile market. Especially in social, if something else becomes hot, users can go away very quickly. It's not like some manufacturing business where you build relationships over years. Some possible risks: * Orkut-like sites were around for a long time, now nobody uses them today. People shifted to facebook and may move elsewhere. * It is possible that a decentralized, autonomous solution may come up for social profiles. * The fact that the company is not mature is a double-edged sword, a new idea or feature may come up that may well make facebook a less attractive place to be.
