They aren't plug 'n play for advertising, though. "How can I find a community for you," is the charitable flipside to, "here's a community you might like to be a part of," where the community is "Coors Lite purchasers."
That's so short sighted though; I'd be so much more likely to engage with an advert that figured out a new thing that would interest me than the usual "you've been reading about sc2 for a week, so have more of the same" nonsense.
Yeah nobody knows how to do that. To the degree that anybody's figured any amount of it out, it's much more likely and lucrative to point that code at changing your vote than your brand of toilet paper (wink wink).
