First you select your theme, then add text, photos and links. Next you publish it and share it using Facebook, Twitter or Email. The best thing is you can do this all on your iPhone or iPad. Granted the sites are very simple, but they would be great for creating a collection of photos while out for the afternoon and then immediately share it with your friends. You can always come back, add more content or switch between the selection of 2o themes.
This continues the trend of simple, effective publishing platforms like Tumblr, Posterous and Flavors.me.
