No, that's not what I meant, just that the situations aren't exactly analogous. You can bet that the $299 fee acts as a wonderful spam filter, while we're wallowing in thousands of submissions that are the equivalent of you submitting your travel reservation service to a travel category for every major state, country, and municipality with an all-caps all-crap description the the effect of "travel reservation, reservations, cheap, low-cost, planes, trains, automobiles, rentals, leases, cruises, clearance, etc, etc." And if they get lucky and two of the 60-odd submissions make it in, they'll just try again a few weeks later.
When the equivalent on Yahoo would cost them somewhere around $18,000 for the first round, I'm betting Yahoo sees a lot less of that sort of thing. I've sure even one $299 fee down the drain for a crappy submission makes submittors seriously re-evaluate a number of things.
Decent submissions are buried in a ton of crap, and that makes it difficult to find them sometimes.
