When I started at Google Nov. '06 Doug had created some awesome Gmail mockups that really took the design and functionality above and beyond and -- having heard about how ground up Goog worked -- I was thinking those designs would be acted upon and built in the coming months and I was excited about using that Gmail.
When I left end of last year, the mockups were still being iterated on, and the only thing that had been built based on those mockups were the buttons. Gmail's just too big, as are search and ads, and UX is too disorganized and outnumbered to have any say.
