It's totally natural for me to shoot photos when I'm on a road trip. Then I get back home, I crop them, select the good ones, and then share them with friends and family. But why shouldn't all the sharing happen while I'm shooting? Isn't that a more natural and socially comfortable way to share my experience?

One way to simultaneously share and shoot is to use metadata collected during image capture. Adam Hertz points to Ron and Taylor's Big Road Trip- a new GPS-enabled photoblog. Adam writes, "the voyagers are on their way from the Bay Area to Las Vegas, posting travelogue-style snapshots as they go. Each post is correlated via lat-long with satellite imagery from Microsoft's Terraserver. Next to each picture is a high-res satellite view. If you click through, you get a larger satellite view, with overlayed thumbnails of pictures in that sector."

There's a ton of room for improvement here. Cameras need to record way more than images. Think about all that's in your head when you take a photo: where are you, why are you there, who are you looking at, why are you taking this photo right now? Look at Flickr, the social photo sharing site. Flickr just added 'notes,' annotations made to photos that a viewer use to help learn more about the photos context. These notes could be the ideas that were in your head when you took the photo. How great if this context was recorded and captured on the camera while I'm shooting! Then we will begin to see a whole new expressive medium emerge.
