The editor needs to put his own life on hold for the better of the magazine, the crew, and the readers. And to have a bigger vision of the magazine's style and an understanding that every [issue] should be well-balanced and hopefully surprising. To have a pink wall with a door of perception where he can bang his head on.
I read a lot and fell in love with comics and science fiction. I even self-published some of my comics when I was 16 or 17.
I had the insane misconception that I was ready to conquer the known universe with Tähtivaeltaja. No mercy!
One person can't know or like everything, so an editor needs collaborators whose opinions and expertise he values and can trust.
I myself wouldn't want to read a magazine that focuses solely on a small part of the literary field or of the popular culture - better to smash the borders and look for interesting and important stuff from many different forms of storytelling.
New writers seem to pop up from everywhere. And quite a few of them are really good and original.
It's also interesting to notice that most of the best Finnish speculative writers are women.
