> Its a shame that "affiliate" ads like the ones they let bloggers use have 100X their ROI...

Sounds like an incredible market opportunity.

What are the companies that are building ad marketplaces targeting high performing affiliate bloggers which demonstrate their value better to advertisers, and share a higher proportion of profit with the bloggers?

Are there fundamental issues trying to scale up a business like this? Not everyone can spin their own custom 'sponsership' packages like DaringFireball, but there is a lot of good blog content out there.

I remember seeing some bespoke ad networks in the designer space, can't think of their name off-hand. Had the feel of a high-end web ring, if that's not an oxymoron.
