I read what I thought was a useful bit of advice somewhere the other day, which basically said don't mention story rejections on blogs or websites as you never know who's reading. In effect, any prospective publisher or agent who's interested in your work could find the posts with a simple search, and where they once wanted to publish/accept the work, they see it's been rejected x amount of times and change their mind.
Also on the matter of rejection, I doubt there's an author alive or dead who's not been rejected hundreds of times. It's something you have to learn to accept. Some rejections are helpful, others come in the shape of form letters. It doesn't always mean the story's no good, just that it wasn't suitable this time. Like countless authors, I've got loads of short stories and 3 novels sitting in a drawer that are no good, or which I abandoned. The interesting thing with them is going back years later and rereading to see how much you have improved. In 1997 I submitted one of the novels that's now basking in a drawer to an agent who represented Stephen King, Dean Koontz and Richard Laymon. He interestingly wrote: 'My feeling is that one day you will have a novel published - GIMOKODAN [which was the title for it then]is very much a borderline case.'
Although the above agent's comment inspired me, not long after that I ceased writing for a number of years due to work commitments. But that manuscript with the crap title - Gimokodan is the underworld of the Bagobo people of the Philippines - still gnaws away at me to rewrite it. One day I will. As with most things, too many projects, too little time.
