I don't even know why I like GitHub as much as I do. I have decided not to pay them as I can't really justify the amount (Dollars are not cheap in Africa) - so I host my repos on one of my Linodes and have them backed up to S3 every day. This works perfectly well, and I have no problems doing it, yet I feel like I am missing out on not having them tucked away on GitHub.
I suppose the feeling is similar to my feelings of Linux vs OSX. There is nothing (apart from Photoshop) that I cant do just as well on Linux, but I still feel like I am missing out by not being on OSX.
Its probably just that it seems all the "Cool People" are using GitHub.
