Good for programmers, good for you and good for me. Emacs is for
advanced users from that view point. From that view point everything
fits into place. 

From view point of users coming to Emacs "Recursive Grep" will not
have its meaning. Or any meaning at all.

It would be good to have a popularity-contest package similar to
Debian, where one could gather statistics what is actually used by
some users and submit that statistics.

Other good test could be to put 5 people together who used computers
for last 10 years regardless of their operating system and tell them
to open up Emacs and find files containing the term "Emacs" and watch
how they are doing.
