You probably have a ton of stuff on the Internet, all contained within your "digital life stream", spread across a seemingly unending list of web services and social networks.

Photo Hack Day 4 erupts April 6th, and runs nonstop through the weekend. The first Photo hack Day brought together photographers, web designers, photo editors, and computer scientists for the first image-centric hackathon. Since the original 200 hackers threw together almost fifty mashups in a single weekend (two years ago), Photo Hack Day has blossomed in number, creativity, and excitement as it readies itself for a fourth rendition. Lead sponsors Aviary and Facebook look forward to "[a]nother full weekend of photo centric awesomeness."
