Google Search Product and User Experience minx Marissa Mayer just presented at Techcrunch50 and officially released Google Fast Flip, launching a service that both David Carr and Techcrunch had spilled the beans about a couple months ago.

Taking off on Google founder Larry Page’s dictum, “Why isn’t the web like a magazine?” Google takes another step in the direction of becoming a content provider and offers up rapid load screenshots of media rich content, the prototype on Google labs including sources like Washington Post, NY Times, UsWeekly, Cosmopolitan (?) and Techcrunch (natch).

The service looks infinitely more bad-ass on the mobile device and not including ads might be a problem for some media sites (eh, hem AP) that don’t have a liberal view of content share. If the reader drives traffic to the site — thus far untested — then other media companies, including those from our fair city, might be more forthcoming.
