EveryBlock, the latest project from Knight Foundation grant recipient and chicagocrime.org founder Adrian Holovoty, is live now. The filming list, liquor license applications, and business license by type (junk peddler, animal exhibition, etc.) listings are my favorites. It's fun to mess around in. Graphics geek note: if you dig down, you'll notice nice uses of sparklines.
My biggest criticism so far is that the news listings (e.g.) overemphasize the headlines over the intros (which are shorter than those on, say, Google News), so my eyes end up glazing over the METRO BRIEFSs and POLICE BLOTTERs. As long as headlines are written for print and not for the Web, a shift that's going to be a long time coming, attempts to scrape news articles are going to have to be creative.
