I'd say it'll be around for 5+ years, since it just keeps evolving itself. Sure, it takes a little while to get used to the new changes, but they introduce things slowly and often instead of just have one huge change. Not saying that I necessarily like all of the changes Facebook makes, but I get used to them and they don't bother me enough to the point that I want to stop using the site.
