New Amazon mag: Day One
(It seems that so far, it's only available in the US. Typically, that is not made clear up front, making thousands of readers waste time trying to find it on their own non-US Amazon site. That is typical not just for Amazon, but for the majority of such instances, it's sad.)
The magazine is currently closed to unsolicited submissions (and I think it'll probably stay so). This is undoubtedly disappointing to millions of writers. But I can understand why. Even before Internet submissions, publishers were already drowning in unsolicited submissions. The so-called 'slush pile' was a never-ending backlog. And with the Net, Kindle, and Amazon, imagine the pile! They would probably get over a thousand stories per day, it would be insane.
And trying to judge the merit of one story can be hard enough, imagine trying to read slush 10 hours a day, it must fry your brain. I can't see how you could even enjoy reading anything for years after having had such a job for any real length of time.
