If you have something to shout, you'll not find a better place to do it. And you can bring the mountain home if you desire it. When anyone can publish, finding something useful becomes a task worthy of Hercules. But as usual, wherever there are creators, there are people who can't create stepping up to the task of editing. Witness my own FireBlade Publications , bringing together Lewis Carroll, Oscar Wilde, and GodsGiftMaggot in one place for your browsing pleasure.
Editors serve as barometers of quality, and most of an editor's time is spent saying no.
Tomorrow, it'll be the writer who says no, and the editor will be in search of quality material. Rather than writers searching for editors, editors will look for writers. It certainly means there will be a lot more junk out there. But it also means that works of limited appeal will still be available to the limited audience they appeal to. It's sitting in a desk drawer somewhere gathering silverfish.
