Take a look at the list of by-invitation-only members on the righthand side of the Deck’s website. I see so many of my favourite websites in that list: ffffound, Kottke.org, Subtraction, YayHooray, and — naturally — Daring Fireball. Having a Deck ad on a site was a subtle indicator that it was trustworthy and that it had a good reputation. That’s something that almost nothing else — let alone an advertising network — has yet been able to achieve to the same degree.
I’m impressed that the Deck lasted so long. Now, I’m curious about how member sites will replace it. How many will take the Overcast route of selling their own ad inventory? How many will switch to Carbon? Who will try a paid membership like Jason Kottke is doing?
