This is just a question out of curiosity. I am wondering how safe it is generally considered to host sensitive data on repository websites like Github, Bitbucket, etc.? Is it safe enough to get rid of all code on local machines and just store it all on there? How about safety in the sense of keeping company secrets? I notice these sites tout big companies like Google and Yahoo use their services, but do these big companies actually store their trade secrets and important company code on websites like this?
Github has a page (http://help.github.com/security), which has some interesting information, that shows they are marketing it as something fool proof like I described. But in practice, do big companies like Google really find that their proprietary secrets and massive amounts of code are really safe from prying eyes and disastrous occurrences on sites like these?
