Why not use Bitbucket or someplace else that offers free private repos?
If you’re some sort of wizard like Kenneth Reitz, it is obviously a different matter. I am not Kenneth Reitz.
It is also tremendously helpful to be able to link to my code directly for help, and believe it or not, doing this has yet to launch me into inadvertent open-source stardom. :)
The same can be said for my Twitter, Pinterest, GitHub, Tumblr accounts, my blog, and so on. It’s more of a general principle at hand, I think.
