The developer community is all about some Twitter today, thanks to the Chirp Developer Conference. At the conference a new developer site was announced. It can be found at dev.twitter.com.
Along with this site, Twitter is offering up a database of places for developers to use location information, a new User Stream API for user actions like friending/favoriting, and an Annotations feature that will launch next quarter and will give developers to add arbitrary metadata to any tweet.

Another interesting nugget mentioned at the conference: Twitter has over 100,000 registered apps.
In other Twitter-related news, the company announced that tweets are being offered to the library of congress, and Google is archiving tweets as well. There will surely be more Twitter-related news to come as the conference progresses.
