I asked for correct spelling and spelled grammar wrong in the same sentence. How embarrassing is that?
Usually I'd agree that the best thoughts are best put short, but as far as the internet is concerned, I've come to rethink my opinion. Of course everyone should be encouraged to express his or her opinion freely, but if someone disagrees or agrees with a certain point, I think a bit of explanation wouldn't hurt, like 'I agree because' or 'I especially disagree on the point that...'
About spelling...I certainly don't want to ban everyone who makes a spelling mistake, my own spelling is horrible, I rather meant the cases of deliberate misspelling. It annoys the hell out of me to see u instead of you, or if people generally never capitalize. I think it's a sign of politeness to use language to the best of your abilities in discussions. Honestly, if I'm having a discussion in a forum, and somebody doesn't seem to think I'm worth writing words out, I feel offended, in the same way I feel offended if somebody doesn't look me on the eyes while talking to me. And the consequence? I spend more time in places where I feel people are more respectful, and I'm sure I'm not the only one who thinks this way.
