You are correct, and I've learned to simply ignore the quick reply buttons (there are at least 2). I'm not exactly a UI expert, but I do know my own (software company) customers dislike having to think. As such, I try to avoid giving them many ways to pull off the same task.

In the FT case, "reply" and "quote" are obviously essential functions. "quick reply" is redundant. I've actually never used "multi quote", but I'm thinking this could be incorporated into the "quote" function.

Just my 2 cents.
