Congratulations to both. Aaron Patterson has done such great work for the ruby community, I'm glad he joined a company that shares his love of ruby and development.
Good news or bad news?
Huge if true. On the scale of "Employer hires Employee".
I'm sorry, but posts like this suck. Who is Aaron Patterson? Why do I care that he's joined GitHub? What does a 2 line tweet and a picture tell me?
Aaron Patterson is very influential in the ruby community. He is currently on the Ruby and the Ruby on Rails core teams, has made many pieces of software, given many funny and helpful keynotes and helped coordinate security responses.
