90-minute Ruby 2.0 Webinar?

I work for a technology company (PBTech.) and am looking to run a
90-minute
overview webinar on the new release of Ruby 2.0 … Anyone have thoughts
on
whether there would be interest in this topic / potential instructors to
teach it / what it should cover … etc. Any and all help is
appreciated!
You can send me an e-mail at [email protected] if you are interested in
the training opportunity or have any advice to suggest. Thanks!
