Found something pretty cool the other day: Columbia Heights Media Project, a website and project designed to show and describe the neighborhood.
The project's goal is to find what sorts of pictures and videos are already out there about the neighborhood, to encourage people to make more videos, and then to distribute them to the media. The site has a ton of content from Youtube and Vimeo, a lot about gentrification. In my personal opinion it could be a bit more balanced, but there's still a lot to go around.
I especially liked this photo essay.
