...look out Google Analytics?
Not likely.
Sorry Yahoo!, but the track record hasn't been so hot lately. The cultural differences between Yahoo! and Google are painfully obvious and apparently unchangeable for poor Yahoo!. The big Panama PPC admin system relaunch hasn't panned out and made for a better management experience. Their copy of the Adsense program still isn't as good as the original. Ergo - I have to believe the product life cycle for Yahoo! Analytics will be similarly reactionary and half hearted.
