I just discovered that on Flickr you can add your photos to a map! So if you took pictures in NYC, you can add your photos to the NYC map. Its a Yahoo map, so it goes down to the neighborhood. Of course, you never want to give too much information about your location.
Also, it looks like Yahoo photos is getting revamped. Just like Flickr, you can add Friends to your page, so you can see their photos when they post them. Very cool!
