One day, one day...I pormise I will learn more about Ruby and the Raidant CMS.  Until then I'll just have to read about the excitement.  John Long writes:

I feel like this was the best of the Radiant presentations I have done to date...The presentation seems to have perked a lot of interest here at the conference. I’ve also spoken with many people who are already using Radiant on their own sites or are planning to use Radiant on a site in the near future. It’s always interesting to hear feedback and ideas about Radiant.

You can read more from Mr. Long through his post,   Ruby Conf Presentation.  He also provides a link to his presentation in PDF format.
