Flickr is a great place to store your photos and share them with your friends. It’s also fun because you can comment on your friends’ photos.
There is now a new feature called geo-tagging. It’s not like geocaching and you don’t have to know the lat/long of the location, just drag and drop it like a pin on a map. Since I put pins in a map of the world on my office wall, this is a feature I really love! Here is a link to my map.
