Almost all waymarks require a picture to be uploaded for creation, and many require the picture for a visit as well.
Wouldn't it be nice when creating a waymark to FIRST upload the photo, and if the photo has geotag data with it that the coordinates, state, country are automatically filled out for you?
When visiting a waymark, before even selecting the category upload the photo first, then the site could show you nearby waymarks. So if I'm visiting a starbucks, I could take a picture, upload it to warymarking.com, and the site would tell me "There are 4 waymarks near this location: (1) starbucks (2) mcdonalds (3) ...." at which point I could select the waymark I wanted to visit.
As more phones have built in gps and camera, more are geotagging the photos automatically such as the iphone.
