A week ago, we reported that the Google Mobile team is using a new tool to track and monitor how popular feature requests are. Well, it seems like Google AdWords started their own similar tool, using Google Moderator.
Looking at Google Moderator versus the Google Product Ideas site, it is the same thing, just with a custom URL. So, it seems like Google product lines are starting to migrate their feature request lists to Google Moderator, some getting custom URLs, so that users can vote on which ones they want to use.
It is a sort of Digg approach to feature requests, which I like.
