If Fluther is more concerned with grammatical accuracy than content why does it not have an entrance exam?

Notwithstanding the kid logging on from the Bronx that snuck on to the site, the guy who managed to connect from some remote island in the Pacific, the young lady who practically self-taught herself from a mission school in sub Saharan Africa who doesn’t have perfect command of English, etc. not regarding them, how come Fluther did not have an entrance exam to make sure all user could at least read and write on an AA college degree level for instance? If they happen to not be born in an English speaking nation or had the opportunity to get a 1st world education or a world class in a 1st world nation it would be up to that user to qualify themselves to meet the lowest bar for spelling or grammar, (so they can tell if Spellcheck, should they even have a robust version, missed something), that will keep Fluther appearing heads and shoulders atop the Q&A ladder; question content an insignificant fact.
