That's only true with webmasters that are too cheap to hire the professional writers here. The majority buy cheap crap, don't like the quality, and are too clueless to realize they're as much to blame as the "writers" they're hiring. They're the ones who publicly bitch and moan about it. Those hiring decent writers (and generally paying decent wages) aren't out there ranting, and it's why some of us have large numbers of repeat clients. Those with bad experiences are always going to be the ones talking the loudest. Those with good experiences tend to stick with private referrals, so their writers don't get too over-booked to take on more work.
Can you back up your claim please? I've only been around DP for 2 weeks and I already worked with 5 different buyers that were quite happy with my work.
