Any user count on Memory Alpha should be treated as prone to error because Memory Alpha's users are pooled with those of other Wikia sites. A full list of editors can be found on Memory Alpha's maintenance page, but the estimate of 80 users is based on a voluntary listing of users (who call themselves "archivists"). Page views, which are easier to gauge, can be found on the statistics page. The Alexa claim is based on a page view comparison on February 6, 2005.
