I wonder how much of Tony from the Burbs arguments are never taken on board purely because his approach to layout and punctuation remain so... idiosynchratic I make plenty of typos (and probably upset Michale P with many a split infinitive - I've never got the hang of those) so I try not to pick anyone up on their own mistakes - but if someone is going to go out of the way to make a point that language doesn't reeaaaaaaly matter then I will probably get upset. No matter how you rank yourself in the grammar "league tables", chances are most of what you have achieved/gotten away with in life so far are because of your ability to translate your cunning/ideas/whatever via language. If you wilfully ignore it's benefits then you stand a much greater chance of being ignored yourself. If you want to do better in anything (argue your points on a forum, get a better job, change career completely, woo a partner) then your ability to understand language and use it properly - in the approriate context - will give you an advantage over everyone else after the same thing Some people are better at it than others and people shouldn't be judged on it alone - but anyone who says it doesn't matter is making a rod for their own back IMO
