Without a doubt. Yahoo have been doing everything they can to clean up their network; and with the new Panama platform they're establishing themselves as being really advertiser friendly.

I believe this will lead to an increase in advertiser spend and this trial they're running with Google will only lead to an increase in coverage for them.

We also have a Google Adsense feed and work with both across our network. Some sites work better with Adsense and some work better with Yahoo. I would be able to advise on any specific sites you guys have as to which solution will work best for you.
