EveryBlock launched today. A good overview of the site is available at TechCrunch.

Here in the Loop (Chicago) it works really well. It has good content and useful information and it’s laid out in a very hierarchical manner, which makes it easy to navigate and find information. There is virtually no learning curve to get used to the site.

As I played with the site, I found myself having fun reading about the missed connections in the area and seeing photos that people had taken in my zip code. At the same time, I was alarmed to find out about the aggravated battery with a knife incident that occurred a few blocks away. When I read about this crime and others like it, I found myself wanting to comment on it to provide or get more information.

Bottom-line: The site does a great job of aggregating information from other sites, but will it become the source of information as well by allowing users to directly contribute? I hope so. Congratulations to the team.

EveryBlock was one of the big winners of the Knight News Challenge in 2007. eNeighbors has applied for funding for 2008.
