Hi,This is one question that is being asked more frequently, so I have started a page [1] on the Wiki and seeded it with a description of one of the projects that I am working with Sling on.
If you are using Sling, and want others to know (and give support), please either add your own paragraphs, or email the list and I or one of the committers will be happy to add a section.
Thanks Ian 1 http://cwiki.apache.org/confluence/pages/viewpage.action?pageId=2852421
