Your answer is no answer at all.
But I'm afraid it is the truth and the only answer you're likely to get.
Try to see things from out point of view. Yes, we care about the quality of the directory, and yes we like to give update requests a higher priority than new site suggestions. While each update request may not take long to deal with (I think it's probably more like a minute than 10 seconds), remember that there are a finite number of volunteer editors to look at them, who have a finite amount of free time that they wish to donate to the project.
Now think how many update requests we might receive every day, and what percentage of them might be people trying to insert keywords into their listings, or otherwise change to non-guidelines-compliant titles/descriptions. You'd be amazed how blatantly disregard the the instructions on the "Update Listing" form.
