I'm predicting rampant Like inflation on Facebook because of this announcement: http://www.inbound.org/articles/view/facebook-graph-search-search-quality-and-the-meaning-of-like (and I explain why Likes result in terrible friend recommendations anyway.).
Yes, there will inevitably be attempts to game it. It will be interesting to see how/if Facebook deal with it.
