I'm a Product Manager on App Engine and wanted to reach out and say that 100% we are invested in app engine and are working to make it your favorite platform. For example, we heard that GAE documentation needs enhancements and we've kicked off a large project to do just this. It's an ongoing effort as you can imagine, but please take a look at the new landing page and managed VM content as well as the left-hand nav reorg we did. Here is the link. More to come of course.
Please give the new set of docs a try and please give us feedback when you see errors or generally when the content is not up to par with what you expect. There is a feedback tool on the top right hand side of every page.
