The Web 2.0 Expo is entering its third year of gathering designers, developers, innovators and entrepreneurs under one room for three full days of inspiring talks. On October 18-21st, the New York branch of the conference will gather, and you (yes, you!) too can submit a proposal to speak.

What can you propose to talk about? Almost anything. Share stories about lessons learned using social media, design epiphanies, customer-service experiences that changed how you do business, or visual communication. Tell a tale about what has and hasn't worked for you in a way that'll appeal to developers, designers, marketings and business strategists alike.

Then, take this idea and turn it into a compelling video proposal. You can propose a talk solo or with a partner, and create a 2-3 minute clip about what your session will cover and what your audience can expect to learn. It doesn't have to be feature-film quality and don't worry about winning any editing awards. Once your video is ready, post it on Youtube, Vimeo or another video-hosting site, and send a link to Web 2.0 Expo by April 12th. The advisory board, including Jen, will carefully watch your videos, and notify selected speakers in June.

If you need help getting started, Web 2.0 Expo has made their own video to help you out: Insider Tips for Submitting a Winning Proposal. They also have lots of tips for writing successful proposals online and a list of this year's themes (including startup strategies, social media marketing, cloud computing and design for satisfying user experiences).
