This is a great collection of 13 Ruby on Rails Screencasts of presentations made to the San Diego Ruby (and Rails) User Group. I particularly enjoyed Patrick Crowley’s ActsAsTaggable Plugin presentation. It was nice to see him talk about the differences between the gem and the plugin and then shows how to quickly implement folksonomy based tagging in a web application. Even though there is no shortage of Ruby on Rails resources and screen casts all over the Web I feel compelled to share good ones in an effort to help my readers avoid wading through some of the lower quality efforts. I feel comfortable vouching for this particular set of Ruby on Rails screen casts.
