Well now LearnMSNET.com has it's own facebook application to allow all our facebook friends to have our blog entries on their facebook profile. I think this is pretty cool.
Learn MS .NET Facebook Application
The app currently is hosted at http://blogfuse.com/facebook/. They allow you to generate a Facebook application and then publish it from their server for $5/month. This is a great idea and pretty cheap for hosting an application. They've done all the leg work for creating the app and you simply have to walk through their application and then voila you've now got a published Facebook application that will contain your blog posts.
