The way I see it, this game features social interactions - but we are lacking the most primary of social interactions, being able to see each other. We have our avatars, but that's a bit like looking at each other at a masquerade, isn't it?

So to me, your conduct in text becomes your 'appearance' for lack of a better term. Your choice of words and your spelling becomes a replacement for whether you are shaven, have washed your hair, have obnoxious body odour and so on and so on. Using text speak in a medium that in no way benefits from being able to skip a few letters other than sheer laziness gives me a mental image of, honestly, a red-eyed slob throwing handsigns as if he's in some kind of cool gang (and news flash, gangs aren't cool).

Don't look like a washed-out bum online, take a moment to spell and express yourself properly!
