With bitcoin ad networks, it's a chicken and egg situation. They can't pull in the advertisers until they get publishers. But the only publishers they've got so far are people who write solely about bitcoin.
Given that devtome has half a million page views a month on a wide range of topics, you should be able to approach some of the bitcoin advertisers and negotiate a deal that's better than what's being offered to ordinary publishers. I did a bit of Googling and
found this list of bitcoin advertisers. I'm sure the owners of each advertising network are on bitcointalk and you could PM them to discuss a deal.
My gut feeling is that for devcoin to succeed it needs to remain within the cryptocurrency universe and not have to switch back and forth into fiat.
Well, maybe with most Bitcoin Networks. But not Devcoin. Devcoin is promoting projects and development for the world outside itself. Devcoin will bring Bitcoin into the future.
