For one thing, there are misspellings and bad grammar all the way through the supposed GM text. No gaming company hires GMs who can't use proper grammar and spelling, just as no TV news network hires anchors who can't speak clear standard English.
actually i've seen multiple screenshots of conversations with GMs where the GM is using no better grammar or spelling than your average young webcrawler. "your" instead of "you're"... "their" instead of "there". the usual.
i wish you were right, but i think a more accurate statment is that gaming companies hire GMs who understand the world of computers and gamers. they don't hire for exact grammar skills any more than the TV networks hire anchors who can act. :-)
