I remember a GitHub'er speaking at RailsConf a few years back (possibly '09 in vegas?). I thought it was one of the best talks of the conference, both in terms of content and pace/delivery. I learned things, it kept my attention, I still remember it today. All that to say–excellent point. Having your employees speak is good for them and good for the company.
