Is there a way that your wonderful Google Tracker could be adapted to do the same for the "new" Yahoo so that we could see the results side by side? Hehe
Probably not going to happen unless they open up their API. Inktomi has an API, but it's six-figure price-tag (plug monthly fees) to get access to it. So for a free tool, it doesn't really make sense. If they open up their API like Google does, it will be added the same day. Another option is "screen-scraping" (downloading the actual result pages), but there is so many keywords being tracked right now that it would be a huge bandwidth overhead, and probably would get the IP addresses banned by Yahoo because of the volume of requests required for all the keyword tracker users. - Shawn
