Honestly, I can't decide.
I have spent the last week submitting a short story I wrote to different journals and the whole process is so tedious, I'd rather stuff envelopes for minimum wage. First, you have to find a journal, then see if it accepts multiple submissions, because I'm not going to live forever and waiting three months to see if one journal is going to publish it isn't happening. As far as I'm concerned, anyone who insists that 'no simultaneous submissions accepted' doesn't want submissions and might as well just close up shop.
But I digress.
After finding a journal that accepts simultaneous submissions, the hunt then begins for their submission page. Then you have to decide what to do if they only accept email submissions? I mean, Submittable.com sites are much faster and convenient, but what if one of the email only sites is the one who'll publish you and no one else will?
It's all just awful.
But I suppose rejection letters aren't much fun either, though sadly I am getting used to them.
I don't know, I guess it's a coin toss.
