I occasionally find this feature annoyingly redundant. If you are responding directly after a post, there is no need to repeat the post. Especially when the original post includes several photos. Just creates unnecessary scrolling. I find myself just exiting out of the thread if there are more than one long 'repeats.' I do find it useful if one is responding to a post that is several posts away, which I assume is what it was created for, and even in that case it would be nice to edit the quote to what one is specifically responding to rather than the entire original post. Just my peeve, no offense intended.
Edited to add: sometimes I'm just an old crank...
