We just use the performance reports, which are on the homepage when we sign in, under our daily balance. If you are not using RSS then make sure the ad type is clicked to "websites only" to be able to see channel data. Clicks are not real-time, though. Latest are from day before.
I'd like more activity in here, too. I figure just not that many are using Yahoo. Most are using AdSense, but we still do better with YPN. I know a number of us check in fairly regularly so if you have questions, etc., I think someone who can help will usually be along fairly soon.
