I browse HN a bit more than I should and I see you and simonw around a lot, like you said always providing thoughtful commentary.

When I write comments on here I tend to spend upwards of 15 minutes to draft and reformulate my comments. Sometimes double-checking what I'm about to say (sometimes not thoroughly enough as some of my recent comments show) and I was wondering if you have a similar experience in that regard or do you just manage to fire off a comment in a stream of thought fashion from start to end?
