People who don't spend a dime do hit "like" on Facebook. True. But a certain percent who hit is will spend dimes (I have). So if the "like"s skyrocket it's a good bet that the dime-spenders are increasing rapidly too. I'm expecting that to happen. To paraphrase Jack Aubrey, "Pet rocks ain't in it." -- that's a reference to a character in Patrick O'Brian's magnificent 3,000 page novel (in 21 or so volumes).
