This week we welcome John Papa to the show to talk about the Open Source Fest at MIX, which is a soirée for open source project leaders to come together to show off their great open source projects, and win some cool prizes! The Fest will be held on the evening of Monday, April 11th from 6:00-9:00pm, and is open to all MIX11 attendees who want to have a nosh, hang with the community, and vote for their favorite open source projects. Prizes will be awarded, but the key is the opportunity to showcase the open source projects created by the community, stir the collective brainpower, and network. There will be food, drinks, a fun Vegas atmosphere, and a chance to meet many of the MIX11 speakers and attendees. If you have a project you want to show off, register by sending your name, project name, link to your project, Twitter ID, and email address to John Papa at jopapa@microsoft.com.
