RailsConf 2010 Talk and Slides
My RailsConf talk Curing DIV-itis with Semantic HTML, CSS and Presenters went off great, with a standing room only attendance and some great questions. I apologize for not having a decent presenter example in the slide deck. I was concerned about hitting my time limit with the slide count (but ended up coming in around 30 minutes instead).
You can get the slides from either the link above or here (9.7MB PDF)
