For most people, myself included, it's not about the ads as such, it's more the tracking that goes with it. I'd happily see ads all day if they didn't track me, but they do, so I use adblocking. Should I unblock the sites I like? Yes, I should, but it's just too much work so I leave it on permanently.
Yes, absolutely. I actually realize I'm missing a significant amount of opportunity right now by not seeing Google ads for products I could make use of, so yes. However, I don't want my IP or anything identifying me in particular associated with my ads.
Potential opportunity here to make a special adblock which tracks user using an anonymous ID code? Essentially acting as a trustable middleman in the equation?
