From the wikipedians by arrival page
/In other words, we Wikipedians abhor the idea that the amount of time
spent working on this website is any sort of indication of how well one
can write an encyclopedia article. Indeed, we distinguish ourselves by
our ability to write good articles, which is what /really/ matters. We
ought to do our best to underemphasize seniority, which can be used,
often illegitimately, as a way of deciding who to accord how much respect./
