Love the idea. For those who aren't as Lambda savvy you might want to provide some "real world" information on pricing. Ex: This code takes roughly 500ms to run, which means you should expect to pay $0.10 per 96,000 comments on your blog.
I know it's stupidly small costs (Lambda is wonderful for that), but some people still don't understand how to translate the pricing structure to "the real world".
