From Joe Stagner:
We launched the Windows Web Application Gallery at MIX on 3/18 with 10 open source and community applications, including DotNetNuke, DasBlog, Umbraco and Subtext.
We are now experiencing thousands of application downloads per week!
Are you working on a community/open source application ?
Why don't you join the Web App Gallery?
To get started:
1. Review the Web App Gallery Principles to get a sense of how we keep a common baseline for user experience.
2. Create manifest files to add to your ZIP package at using the Application Packaging Guide.
3. Submit your application. (You’ll have to log in with a LiveID first.)
We’ll then check out your submission to see if it follows the Web App Gallery Principles.
Once it does, your application will be live to download in the Web App Gallery by Windows users!
