I use it to separate and scale parts of my application. More specifically I am building a continuous integration application in Ruby and using SQS as build and result queues from which EC2 instances pick up tasks, builds them then add into the result queue. I don't need ordering and don't mind a few seconds of latency. PS: If you are interested in beta testing it please drop me a line.
