Ask HN: I need help gather data-sets and API suggestions for NYTimes Hack Day

I'm trying to build a comprehensive list of new and interesting data-sets, tools, API's for the TimesOpen Hack Day in December. The goal is a quick-start page for people to get up and running quickly with whatever project they decide to do. This would ideally would be useful for other events too. - API's beyond the obvious - Frameworks - Classes, wrappers, and such - Open source projects that can be utilized - Sample code - Data (interesting, useful, electoral, esoteric...) Please feel free to re-state the obvious stuff (Google, Twitter API's, PhoneGap, JQuery docs and such) since you never know what might get missed. I'm hoping to provide a few Xbox Kinects for people to dev on so anything else beyond whats already on openkinect.org is be welcome. Not to plug the event, but to get more info on it: http://nyti.ms/tohackday http://open.blogs.nytimes.com/2010/11/22/timesopen-hack-day/
