Can I throw all these suggestions in for people to chew on:
Perhaps expand on this idea to include such features to allow users to create, find, save and share; routes [events/shows], sightseeing [geotag photos/ panoramio], Amiga galleries [ie: Flickr/ link back to user_cp].
Maybe add website addresses or links to [amiga.org/ et al] user profiles, msn, icq, email etc.
Include the Google 'MORE' for Photos/Videos [youtube accounts], Wikipedia, Webcams.
User search tool.
Then your project could look really pretty:
