Today, Twitter is kicking off its first ever developer conference, Chirp. Speakers include Ev Williams, Biz Stone, Ryan Sarver, Dick Costolo, and John Battelle, who will be speaking on topics like Twitter’s @anywhere platform, geo-location, monetization, and third party developers. The last topic, in particular, will likely be an ongoing theme throughout the day, as Twitter will need to explain to developers how not to fill holes in its product but to instead build their own killer apps. And through all of it, there’s bound to be plenty of announcements. I’ll be taking live notes and covering breaking news throughout the day (we’ll include links to each new post below).
