It's just my opinion but I would say that many Google products really suck from usability standpoint. I use computer all the time and I would say that I am pretty advanced user... and yet I think that sometimes it is really difficult to quickly find something in Google Analytics and I think it's UI is counterintuitive and user unfriendly as hell. And I have to admit that I hate Google Groups - when I am searching for a solution to some problem and I see something promising in Google search results I just continue searching when I notice that the result goes to some thread in Google Groups and I don't bother checking that out - if I were looking for the example how NOT to do this I would use Google Groups.
