I think eBay have tinkered around with it too much. It can be extremely helpful (and entertaining!) to see what others have said about a seller and/or an item, so it is a real shame the system seems to be on the decline, with noticeably less feedback being left.

As far as viewing feedback is concerned, it only used to take a couple of clicks to get to the feedback page and find what you wanted to see. Much more fiddly these days.
