I really liked the concept of this article. I've been impressed by your other posts and just wanted to thank you for the insights you provide. As I get closer to launching my own ideas, I can't tell you how helpful it is to learn (or attempt to learn) from the experience of others like yourself.
A side note - I noticed you're using slicehost. With the "cloud-y" providers available (Heroku, AWS, etc) would you ever consider a move to them? Could that help eliminate any of the moving parts, or just relocate them?
