ApolloHunter.com is a simple site to download, upload and share Adobe Apollo apps! This is a great site to see who is doing what in Apollo development. Maybe by the end of the summer you will be able to see something I have done on this site? 
Three new cheatsheets for developers using and getting started with Apollo. All of the new Apollo Classes are on the sheets (and a few updates to existing AS3 Classes). There are definitely some cool new Classes including but not limited to: Apollo Application, HTML, HTMLControl, File, FileStream, Shell, JavaScriptObject, Shell and more.
Although I have been developing in Flash and ActionScript 2.0 for a wile now, I am totally new to Flex, Apollo, and ActionScript 3. These cheatsheets will come in handy for everyone, not just the newbie. Hope to see a paper back in this to keep on my desk sometime soon.
