Well, it turns out that she might have been planning a move because today Bloomberg reports that she’s taken a new role in charge of Location, Local Services.

Location is obviously the new frontier with armies of mobile phones being outfitted with local services.  Google’s (GOOG) Android OS will no doubt be a huge part of Mayer’s new sphere of influence.

Mayer joined Google in 1999 as one of its first 20 employees and first female engineer and since then has worked on Search as well as a lot of other important projects including Orkut and  Gmail, focusing on UI design.  She’s known as the gatekeeper, the one who decides when a project is ready to go public.

Also of note: Google has chopped all but the top management off its corporate Bios page leaving Mayer and many others in the webcaches of the Internet.
