These are full web applications which you can play with. Note that they’re not necessarily fully production-ready, but they generally work more than not. If you’d like to use them for something more robust, feel free to contact me.
These are plugins I’ve created for the blogging software I (and many others) use, Movable Type. I primarily create plugins for Action Streams, which are very small, but people find them useful. You can see all of them demoed on http://ussjoin.com.
Open Web Lecture
I had the opportunity to give a guest lecture today. The course is called “Developing Photo and Video Applications For Online Social Networks,” but it’s essentially a course about developing for Facebook. They asked me to lecture on the alternative– namely, developing on the Open Web, and what that’s all about anyway.
