Finding packages to enable by default

[Tom]

It's been said in the uniquify thread that uniquify is one of
those packages which most users enable if they know it exists. I
agree and finding similarly useful packages which could be
enabled by default would help improving the initial user
experience.

In order to find these an elisp function could be written which
outputs the name of those packages which are shipped with emacs,
are disabled by default, but users enable them. This function
then could be sent to this list and other emacs
forums (emacs.reddit.com, etc.), so users can run it in their own
emacs and then send the output to some adress or person.

There the results can be summarized and those of these packages
which are enabled by, say, 75% of the users, should be enabled by
default in emacs.
