> I'd say the problem for mainstream users is that some apps are too targeted: it may be both effective (and the most cost effective way to advertize and reach your audience), it's also creepy to many users. This was Target's realization, was it not? They were doing super-specific targeting and analytics, like sending coupons for pregnant women (to the ire of a teenage woman's dad,) and later switched to "hiding" the coupons in irrelevant coupons so the pack looked more generic. Personally, I'd much rather receive the focused coupons. I'm not going to stop a company from learning about me unless I go paranoid, so I might as well receive insight as to what it thinks it knows. Five minutes ago I thought that Amazon, Netflix, and Pandora simply couldn't nail my tastes, but perhaps they're in some long game of not creeping me out and knowing that I'll return _some_day_.
