jjx here. This is not propaganda, nor is it incendiary. It's the truth. I have been promoting App Engine to everyone I talk to, because of the ease of deployment and the promise of scalability. I have been waiting for months for the beta quotas to be lifted. My wait has been in vain. It seems that scalability to Google means it will scale on one little machine in their infrastructure. If 500 requests per second is the best I can get from "10 years of knowledge Google has in running massively scalable, performance driven systems", then the hype of Google is a fiction.
