The Twilio Developer Contest is now open for submissions until November 28th, with a grand prize of a Graphite Kindle 3G, a $50 O'Reilly gift card, and $100 in Twilio credit. Two runners-up will also receive $100 in Twilio credit. This contest allows previous entrants to participate again, and the deadline is approaching, giving developers ample time to build their project over the holiday weekend.
