i think that utility is different from social. Search is a utility that competitors have offered incremental improvements, that while useful.. to most people don't matter. Example: how many people test search results in multiple engines, to determine which one is giving better results ?. At this time, on any search engine, if you can find what you're looking for most of the time, in the first few results, you just stick with it. Where as social is just that its whats cool/hip and something your friends are using. I think you underestimate the value of virility. Services like Instagram and Tumblr, are all very good services that are social and could possibly unseat what we see now. People and not just in the tech circle are always trying out new cool/hip social services. If some users think its cool, convince their friends to join and the cycle starts over.
