It doesn't sound like the OP tried very hard to contact them. He sent them an email, didn't hear back, and then decided to write a blog post about it. I mean, if he cared that much about github, he would send them an email back asking what was up. Or 5.

There are always things like real people and phone numbers. You know, find some GH staffers via G+, LinkedIn, Fb or your own network of friends and work some connections. Pete does not say the lengths he went to, but email is admittedly one of the most passive mediums.
