I'd like to grab purpose-built functions that do one thing well, not "giant applications."
Some examples:
* A URL shortener that works.
* An authorizer function suitable for casual "the password is X" that doesn't need a full-blown auth story.
* A URL validator. Send it a URL, it checks the link.
I'd love a turnkey application that has a "status board." Each light invokes a user-specified Lambda function with a given input. When the lights are all green, it "passes."
