Depends on which side of the process you are on. If your are the FT guy who does the approving it's like "Arrgh, new articles are backing up again, didn't I *JUST* approve a bunch only a few days ago?".
If you are the guy who sumitted a new artical and are waiting for approval it's more along the lines of "Arrgh, It's been hours/days! Did I do it right? Is it good enough? Is it on the reject list and they haven't told me yet?"
So, the answer is 'It depends".
Seriously, it's like that. Was like no time at all after it was put up, but before it is it's forever. Think I had one wait four days. Forever.
