I naively contend that advertising is currently at a local maxima, but not at a global maxima. I contend that for a really successful advertisement framework two things must happen: (1) Ad relevancy must be above a very high threshold, else users will filter out all advertisements, even if some are relevant. This threshold is demographic dependent. (For HN crowd, I contend it would be around the 90% mark...I, for one, still ignore gmail advertisements). (2) Users must trust that the advertisement will give a good deal, else they will just go to Amazon, eBay etc to buy the product instead. I think trust is an often overlooked aspect of advertising, and is a difficult problem to solve. If ever I get around to building an advertising framework around my app, I will attempt to err on the side of not running advertisements rather than risk losing the relevancy and trust battle.
