Yes, I used to do a fair amount of consulting (aka nothing works properly, fix it, have this bag of cash) and I frequently ran into 'projects' that had no source control or had <projectname>/1 <projectname>/2 <projectname>/2a_1_fix_foobar :|.

One of the things you'll learn if you hang around Hacker News/online programming communities is that a lot of the people in those communities are at the top end of the spectrum (there is a degree of self-selection that means a higher proportion I think).

It's pockets of relative sanity in a sea of disaster.
