Although we have https://www.dokuwiki.org/popularity
for showing the most important general statistics gathered by the popularity plugin, a personalised direct feedback would be nice.
A user mentioned an idea in the forum [https://forum.dokuwiki.org/post/34868]:
"It's a shame the popularity feedback plugin doesn't have a way to to rank your wiki against the group ( "Your wiki is larger than XX% of other dokuwikis)."
While it probably isn't feasible to display anything real feedback in each wiki itself (because it would need to be saved in the wiki as well), update.dokuwiki.org/pop could get enhanced to take "anon_id" and compare that installation with others. The very least the plugin should feed back is a link to :popularity.
