I don't know... less than a year ago I didn't even get an interview because they were (legitimately) concerned with my lack of experience with Haml and Rails.
I mean, kudos to them if they changed their view on this. I just wanted to let you know about my experience on the topic at hand.
I think we had the same view a year back but the bar is higher when your experience is less relevant. Of course we make judgment errors too, feel free to reapply.
I promise that your open solicitation to GitHub http://octohire.me/ was not held against you :)
