Our account has been updated to the Y!WA 9.5 version and it is simple awesome! We will be posting the new version review in a few days, keep in touch.
One of the Yahoo! Web Analytics 9.5 new features that I love is that you can drag and drop a call out icon to any place in the chart and you can add your insights or additional information. I love it because it adds a lot of relevance to your analysis. Enjoy some screenshots.
