My talks at RailsConf were a ton of fun. The first night I did talks on Merb and jQuery which were completely packed, and the first day of the conference I did a talk on DataMapper which seemed to be well received as well.
While it was nice to hear that so many people wanted to see the DataMapper talk that some people were turned away, it sucks that some people got turned away. Without further ado, go check out my Merb and DataMapper slides at Slideshare:
I'll try and get up the jQuery slides shortly as well. Enjoy!
