I didn't know if they used git or hg, and I wasn't necessarily having a go at either. The poster obviously thought that there was less friction to an online edit, so you have to ask yourself why that is?

Perhaps they don't like fiddling about on the command line, their IDE is too klunky, file managment is a pain, their version control interface is convulted, or they are not sitting at their computer with their codebase - who knows!

Either way they appear to find it easier that way.
