It's usually a good idea.

No. This is not how `umask' works. Whatever value `umask'
currently has is logically-AND-ed with 0666. This means that by
using 027, the result is:
$ python
>>> print "%04o" % (066 & 027)
0026
These are the bits that will be turned *off* for new files (see
the umask(2) manpage for details), so to find out which
permission bits are allowed, you have to use the reverse mask:
>>> print "%04o" % (0777 & ~(066 & 027))
0751
The 0751 allowed-bits mask is equivalent to:
rwxr-x--x
This means that with a umask of 027, you are effectivelly
allowing only the bits in ``rwxr-x--x'' to be turned on by
default for new files, and this doesn't include write permission
for the group.
I know that the whole `umask' concept is a bit tricky to grasp,
since it depends on knowledge of numbering with an octal-base
*AND* it works in the reverse order of that people usually think
it does, but hopefully, with the help of our excellent manpages
and a bit of experimentation, it will become more obvious :)

Nah! Never apologize for a question. There is no such thing as
a stupid question for this list (well, unless the question refers
to Windows, of course :P).
