Sorry but I still don't by the visible argument. Do you really do
check what is inside ~/bin
before running every command? Even if you do that I do not need a
survey to claim that a
majority of user simply do not do that.
I do, actually... because I put stuff there, so I inspect its contents
periodically when I do. However, my claim above is not about me. I did
not claim that a majority of users behave like me. What I said was,
that you could probably measure, by survey, whether or not the two
directories on the path were equally visible to users. I can say that
the two are not equally visible *to me*, but I'm not going to claim
that they are equally visible to the average user, or even the average
security-conscious user. I *suspect* they aren't equally visible to
certain significant subsets of users, but since it is probably
measurable, I'm suggesting a means to find it out instead of
speculating based on my own behavior.
