Somewhat related to the We have tons of synonyms, now what? question.
Minor nitpick on the synonym proposal UI. The master seems to always the one with the "highest" number of occurrences. However, when the numbers are pretty similar (within a factor of X, (X ~= 30% or something)), perhaps either one should be allowed to be the master.
According to the massive response to the retag request for these tags (7 votes among 3 answers),
emacs-lisp was the winner. Yet that tag currently cannot be named the master because it has fewer votes.
Should the threshold be changed to take into account numbers of tags that are within a certain (small) constant factor?
