I would have to disagree with that.
If I were going to write 10 unique articles and submit one to each site, then I would only get 30 backlinks. But if I submit all 10 to each site, then I get 300. If you spread your links around to a lot of different internal pages, this can do wonders.
If you use a different title at each directory, at first, you will probably see the same article ranking multiple times, but within a few days, Google's competition filter catches up and usually only one remains. But in those few days, you get more/extra organic traffic.
Also, you will be getting your articles in front of more people that syndicate them for newsletters, memberships, etc... Not everybody uses EZA, you know.
There are a few other reason that I will keep to myself right now, but given the choice, I would submit every article to all of the sites on my submission list...which does not only include article directories, of course.
