I had the honor of meeting Daniel O’Neil, with Everyblock.com. He has quite an interesting website.
The goal of everyblock is: collect all data that can be geocoded, and organize it for user search.

Basically, it’s like a newsfeed of your block.

What can I do with everyblock besides scan the crimes near me? Films being shot, flickr photos and blog posts, new businesses moving in near you, and general news- accurate to within your city block.

Daniel thought it would be interesting to integrate twitter feeds into everyblock; and create a social newsfeed alongside a geo-newsfeed. As I pointed to the wall of Argo Tea, and imagined a digital display with a social and geo news feed of this city block.

Other clear applications include real estate prospecting, learning the culture around a vacant apartment, even monitoring geographic trends for stock market appraisals.

What would you do with Everyblock data? Daniel says there will be an API- some day.
