Been to MOSH lately? If not you'll notice a new look next time you go there. The site is reoganized slightly and the experience when you browse and upload is slightly different. Most notable is the seek visibility... you can seek for items based on name, title, tags etc... so for example, seek "maps" and whenever new content gets posted that meets your criteria you'll be notified. Or, if you upload something you'll then be notified of people that are seeking what you just uploaded.. quite intelligent really. See http://mosh.nokia.com/user/gisuser
FYI, MOSH is a resource that enables users to mobilize and share any of their content - we share wallpapers, images, videos, newsletters, and other items of interest.. all accessible via mobile as well.
