There is an iPhone app that is quickly becoming my favorite thing.
It is called Instagram.
It is basically facebook combined with twitter. You basically can follow people like twitter ...or facebook...and you can share snippets of your moment to moment adventures using pictures. The pictures are taken with your phone of course and there are instant editing choices to give them really cool looks.
Here are a few instagram images from our vacation so far...
If you "instagram"...let me know :)
