The place of grammar and spelling in logical discourse.

Ok, you can call me a snob if you like, but in my opinion, not taking the care to make sure your written communications are free of misspellings and misused words reduces the force and power of your arguments. It also reduces how seriously I'm going to take anything one says.

I don't care if it's email, a LiveJournal post, or an academic paper. Like the old saying goes: If you cannot say what you mean, then you cannot mean what you say.
