Well, unfortunately, we know that far too many of the "worthy" submissions get chainsawed along with the "unworthy" when the queues get too big.
ODP can implement all the editor tools they want, but the bottom line is that a human being has to go through each and every one of the submissions to ascertain which should be included and which should be deleted. The only remedy for the problem is to add more editors.
I know that two years ago, only about 10% of applicants were accepted. I haven't read anywhere that that has changed.
