I'd also put under the heading "decent" some consideration for your readers, making sure that what you post is sound, accurate and based on the fact you've done a little homework so that you don't end up spouting uninformed statements. A good opening post along those lines is a great starting point for a discussion. It isn't a great starting point when the poster hasn't had the good grace to ensure that you're not mired in delving into what he says before you can trust a single word of it.
