I wouldn’t be so sure. I mean it’s anecdotal, but I rarely buy things. I buy all my clothes from the same internet store, and I do mean all, I have five pairs of shaping new tomorrow pants and when they get worn I replace them with the same damn pants. I heard about them from a coworker who uses them. Almost all my purchasing habits are like that, and I suspect I may not be the only one on HN.
I do click on the occasional Kickstarter boardgame advertisements, but I never end up backing because we always end up playing bloodbowl anyway.
On the other hand I do subscribe to the internet part of a Danish news paper that along giving you access to articles also removes all adds for paying users. I guess that’s sort of what brave wants to do, but who wants the hassle of buying alt-coins and reporting the taxes on it?
