A few of the photos that flow through Picasa to Panoramio end up on Google Maps. (It's only a very few. See here.) Some examples include:
* The DC Metro
(original shot : DC-subway-Gallery-Place-i-nhgriplanning-.JPG )
* A CT House
(original shot : House-w-Flag-on-Westway-Rd-in-Westport-1.JPG)
(original shot : Trip-France-UK-i0wtsysbio-5.JPG )
* Pop Sign Downtown in NYC
(original shot : POP-sign.JPG )
* A statue in front of the Prudential Center in Boston
(original shot : Statue-in-front-of-Prudential-Tower-i0ismb10-3.JPG )
Panoramio also supports a very interesting "look around" feature on some shots. See, for instance, what it does to my photo of Notre Dame .
My overall access stats are also available.
