Momus, announcing the retirement of his Click Opera blog (not immediate but soon), mentions a downside of online discourse:

"Sure, Click Opera has been a sort of karate course, and its comment facility has taught me to be more dialectical and -- above all -- the skill set of prolepsis, of anticipating reader objections. But is a more moderate, accessible and dialectical me really what the world needs? Doesn't the world need an immoderate, outrageous and concentrated me, just laying out things that only I could think, no matter how wrong they may be?"

Yeah I agree prolepsis sucks, it seems to have taken a lot of the categorical oomph and thrust out of writing, unless you're just utterly bullheaded you will inevitably find yourself riddling what you do with qualification and nuancing...

Strangely, prolepsis rarely seems to afflict comments boxers... but i guess they can shelter under aliases or "anonymous," they don't have to own their utterances in the same way
