For years we seemed to get by just fine with only a dozen or so editors, half of which were rarely online anyway. I don't know when it happened, but while I had my back turned, I now notice in surprise that there are 44 (!) editors. Even though in absolute terms, the number of top-level nodes created has been declining since 2001.
Maybe that after the great level-reorganising because there are "too many votes", people could also reorganise the editor/janitor/consideration system. There are a lot more people now with powers to consider nodes for deletion/retitling/editing than there were five years ago. If there was a problem with the votes, there might be one for the editor process as well.
