So, I created http://www.islandofmisfitpatterns.com . We'll post anything that people submit - it doesn't even have to have been rejected in the past. After all, I'm usually too lazy to make sure my pattern exactly fits the format that online magazines want. We'll take essays or articles as well. Just send us email at email@example.com .
We've got a couple of patterns up now, with more to come. We're not looking to make money or anything - I just have the world largest hosting plan, so I have plenty of space to play.
