EveryBlock

[6] EveryBlock maps plotted a mix of commercial, government and nonprofit feeds that were geotagged by location.

Users could experience a blend of Flickr photos, recent crime reports, 3-1-1 calls, permit filings, local news stories and home foreclosures that could be viewed as a map, list or RSS feed.

[4] While EveryBlock did not last as a standalone business, it was considered influential for its impact on the open data movement in local governments, and custom maps on top of Google Maps.

As a condition of the Knight grant, the EveryBlock source code was made open-source.

[1] Holovaty has written that Kevin Systrom, the CEO of Instagram, had emailed him to say that he learned a lot about the Django web framework, also co-created by Holovaty, from reading the EveryBlock source code.
