_plus, thank you for your advice! I've considered doing a screencast and will create one as soon as I'm back from my travels. I built the tool mainly for dogfooding my own products and figured I'd build a marketing site to see whether there's any interest.
Re: YAML configuration, that's a good suggestion. I wanted to keep the footprint lean and uncomplicated, so I figured swaying away from config files in favor of Sinatra settings was consistent with that philosophy. YAML would be effective for environment-based configuration.
Thanks again!
