Huge annoyance. It got much worse with an update I received about a months ago. The quoted text is by default collapsed so when you want to reply quickly to someone, you won't even notice you're top-posting.

I tried to contact support or fill some feedback form to no avail. I eventually gave up.

Anyway, this is how web apps ride (no a single day passes without me ranting about the current trend, which I find alarming).
