1. one of the big reasons why online advertising has done so well is simply the negative one: online micropayments were a disaster, and never took off. But they’re much more compelling as a business model, and there’s a decent chance that at some point in the future the financial system as a whole is going to get its act together and put together something which actually works and which people are happy to adopt. At which point, the online ad industry will face a major threat…

    advertisers still think that click-through rates mean something, and that a higher click-through rate means a better ad. It’s the measurement fallacy: people tend to think that what they can measure is what they want, just because they can measure it.

    In fact, with very few exceptions, I’ve never even wanted to look at online ads: its quite astonishing, the degree to which we’ve collectively trained ourselves to ignore ads when we bring up a web page. And what that says to me is that online advertising is missing something really huge.
