Hi everyone, I'm Chris Wanstrath.

When Jeremy asked me to come talk, I said yes.  Hell yes.  Immediately.  But
then I took a few moments and thought, Wait, why?  Why me?  What am I supposed
to say that's interesting?  Something about Ruby, perhaps.  Maybe the
future of it.  The future of something, at least.  That sounds
keynote-y.
