I had the Alexa rankings for Hacker News in there the last time I edited it, but a Wikipedia editor has deleted that reference in his or her infinite wisdom.
Sadly, I was talking more about the wikipedia I would like to see than about the wikipedia that currently exists.
Personally, number of people using something is a lot more meaningful to me than number of journalists writing about it. Of course, as a very occasional anonymous editor, I suppose I don't have much right to complain.
