Or most people hated it but didn't love the product enough to care to comment. Perhaps the design of the feedback form matters. I wasn't part of the beta so I don't know how they asked.
They didn't ask, you have to go into the feature view menu (under profile) and then click a link there to go to another page and then have a form to fill out.
They know UX for sure!
Maybe we should send them a copy of Don't Make Me Think
