I've developed a fear of being beaten to the post... expecially in TCTI. That's why I either post a reply or go advanced, just to check that nobody has beaten me, then I click preview once more, and then quickly click. I don't normally get beaten that method.
For other things, I've gotten into the habit of either quoting or post reply because quick reply is down the bottom, and scrolling down the bottom takes LOTS of effort. If I'm creating a thread, it's default is in post a reply, so I can choose for that... and... yeah, that's about all.
