After a brief face-to-face overview of zembly.com, Todd Fast gives us an extensive demo of what zembly.com is and how it does "social programming."

We walk through the modification of a simple favorite movies application in Facebook, and then dive into how zembly.com helps "casual programmers" develop, find, and extend applications like these.

I liked walking through this demo because you get to see the workflow of creating applications and see the actual features and services that zembly.com provides. Also, I have some fond reminiscences of the Spicegirls and horizontal scrolling.
