GitHub is a social network, indeed

Today I have received a letter:

Hello Oleg,

I’m a Io newbie. I was watching some of your sample code on Github (loved funnyFactorial ;-) when I discovered your “learning french” subdir. I’m french and would be pleased to answer / comment / whatever about that language (not so human).
