I think the reason there's a sudden interest/spike is coz it's it's strange/new/funky.
It's kind of similar to the "You should follow me on twitter." which supposedly inc. ppl. doing it. But I think the initial increase was just interest coz of the strangeness/quirkiness of the statement. Once everyone starts doing it, it will loose it's uniqueness flair and ppl. will just start liking/following as they normally did.
