The Twilio Developer Contest is a weekly competition that encourages developers to try Twilio for different use cases and industries, with the goal of finding success and solving problems using the platform. The contest offers prizes such as an Amazon Kindle 3G and $100 in Twilio credit, and provides resources and services to help participants get started. Developers who have previously submitted but didn't win are eligible to resubmit their entries, and can find additional support and inspiration on Twilio's forums and community hub.
