"If I were a search engine..."
and users googled funny cat pics, saw a cat, lolled and 10 seconds later +1'ed
compared to googling "anatomy of a search engine" and 30 minutes later +1'ing I think it's a valuable metric in understanding bounce rate for particular queries as well as spotting fake +1s.
