Github is already my favorite 'social' network. No need for cheesy photographs. I realize that it's probably considered humorous among some, but to me the landing page is really cheesy and off-putting.
I wish Github had some sort of discussion system. At the moment everyone seems to be using google groups but that'sa pretty awful place to discuss code.
I agree. Although it seems they recently (a few months ago, anyway) took out the ability to message members on the site, which seemed odd. Why would you not want people communicating? Now if I want to get in touch with someone I have to either track them down outside Github to find a Twitter or email address, or I have to comment on a Pull Request or create an Issue or something.
