Multi-users server, or NFS-shared $HOME, yes, expose every working
tree and therefore directories to other users. But still, the good
practice would be to distinguish your working area, and a "clean"
area if you want to get all the power of distributed version control.

One of the main points in having version control distributed is
precisely to allow you to distinguish private things and published
ones (i.e. commit != push). Linus explains this better than I do in
his talk:

You _can_ expose your working tree directly to others, but if you do
so, you'll have to forget about "git commit --amend", 
"git reset <anything-else-than-HEAD>", "git rebase", 
"git filter-branch", ... (any history-editing feature of Git indeed).

OTOH, the common setup for people is to have a workstation (laptop or
desktop) without a public access (for example, my home computer is
switched of when I'm not using it, and my office station is only
reachable from outside with ssh), and to publish things on another
server. So, in the common case, the distinction private/public is
natural.
