I'm using Google App Engine in a new project ( http://www.homeyplanet.com http://www.homeyplanet.com - allowing travelers to share their favorite spots off the beaten track) and I have to say I am very happy about it. This project requires geo spatial queries, so at first it wouldn't be a good choice given how inadequate the datastore is for it, but the trick is always to think how things work in GAE and see if you can optimize it. It only scales well if you do it their way...so it won't work for everything, but most problems can be solved quite well, you will just have to scratch the way you normally would solve them. Note: I noticed that some have accessed the site from this link. The site is beta and is newly launched, and for now we are only covering Europe. If you want to check out how fluid are the geo spatial queries, you can try checking out Portugal, where half our spots are now.
