Web site wireframes
Whenever a Web service that I use changes formats, I seldom complain. Facebook has done it twice in the last few years, first introducing the stalker-friendly News Feed and more recently with its design overhaul. As long as I can be convinced that the changes are intended to make the site more user-friendly and aesthetically "cleaner," I am on board with it. WordPress is next on the list for a significant redesign, with the team producing a wireframe document discussing each of the changes and the rationale behind them. I really like the idea of wireframes as a design workflow model.
