Who needs Adsense?

Adgridwork is a newly launched service that allows you to incorporate text ads onto your website, and advertise online for free. It's a glorified link exchange of sorts, becoming the middle man for link swapping that has become key to start-ups and self-published websites in underground and mainstream web culture.

Your success in using adgridwork is synonymous with the site's success, given the symbiotic nature of a link exchange system. So they've become rather eager in their efforts to quickly publicize their recent launch, and hope to gain members to utilize their service. With the simplicity of account set-up, site additions, and ad tracking tools, their usability is attractive, as are their anti-Google antics.

There is a growing number of Adsense competitors. Will any of them become big enough to knock Adsense of its perch as number one?
