That is because you need around 100,000 uniques a month (around 1,000,000 page views a month to get accepted). I took a look at it. Does anybody know about DoubleClick. I see quite a few big sites using them.
I can provide that; hopefully I get in. As for double click -- they no longer run publisher/advertiser type things anymore. They provide the infastrucutre and other things for advertisers.
Yes, GN's criteria is quite high, but it's mostly about the quality of your site. If they like it, and you can provide them with some good customers, they'll take you. But of course it doesn't cost you anything to apply, so why not?
If sites like ebaumsworld are using GN I am most certain I can provide similar traffic. What type of rates do you see with GN? BTW, is that Jessica Alba in your avatar?
