Ruby on the Web with Sinatra

I've been messing with Sinatra on my personal site. I think it might be a great place to present live examples of some of what Brandon talked about last presentation. I think Sinatra is a great place to start because it's easy to understand and with little effort you can be writing code that has a demonstrable affect.

I'd be willing to make this presentation next month, building on the the basics Brandon outlined. We could consider this a code review session as well, since I'll be showing off some code I've written. John, Brandon, Matt, and others with more experience could chip in and demonstrate how I might write it better.

Thoughts?
