"I just got an idea that will make a great blog post ..."
"No, it won't."
"What? I didn't even tell you the idea."
"I'm not denying that you had an idea; rather, I claim that it won't make a great blog post, because you won't write it. You wrote two nontrivial posts last year and then abandoned your blog for six months. Obviously, you're just like all the other millions of bags of human refuse who think of themselves as writers and yet never write. They never change, and you've shown by your behavior that you're one of them, so why should I believe you when you say you're going to write something?"
"Aww, are you offended? Is our little soi-disant 'aspiring rationalist' incapable of handling a honest statement of the undeniable truth?"
"No, I'm not offended. I disagree—"
"—but I won't argue with you. Just—stay subscribed to the RSS feed, will you?"
"Oh, but of course. It's not like anything will appear in it."
"This is the part where you threaten to drown me in a veritable deluge of good writing, and then I continue to mock the pathetic cycle of failure and self-delusion at the center of your existence."
"Let's skip that part. I'll see you later."
"I know what you're trying to do! It won't work!"
"I never said it would work."
