ZUCKERS, the end of the article is the best... There is an important caveat. It remains to be seen whether ordinary Facebook users will feel comfortable buying things with no more than a tap on their phones. http://bits.blogs.nytimes.com/2012/08/23/deal-will-allow-one-tap-purchases-through-facebook/ The article and other pumper analyst also don't list that a fifth of the users are under 18. Add that to the fake and dupe accounts.
