In reply to Steven Gliebe.

Indeed. And while a more direct reward would be nice, not seeing ads that are irrelevant or maybe even objectionable could be considered as one.

I mean, there may be times when you might even want to see some ads, when you’re looking for something, and most definitely there are many things you don’t want to see. So don’t track, but instead let people freely choose what they’re interested in AND also what they do NOT want to see, and then pick the ads first according to the topics of interest, then if there aren’t enough from those go through all others while avoiding those specified as not interested (though since the ad space remains the same, if there won’t be enough ads available without avoiding those, or for those who’d put pretty much everything in that category, some will out of necessity be picked from it too).
