They're words that creepy marketeers use. They imply something to be commodified, harvested, taken advantage of.
But frankly, that's just what makes it a handy term. Whoever uses it is instantly identifiable as someone who doesn't get it, who simply wants to exploit their, uh, users, who probably won't be around too awfully long. So I would just as soon it stick around so I can easily tell who's real and who's clueless.
