Most writers either have a website, blog, Facebook, Twitter or some other media outlet. I'm here to warn you that anyone can look at your website and read your blog. Facebook and Twitter are open to all the strangers you befriend. One thing writers should never do is post the number of publishers that have rejected your story. Why you say?
The why is because these days' editors, who receive proposals from you will go to your website to check out your work and read your blog before they look at what you submitted. If you sent X-Story to editor at Y-Publishing and she/he reads that the story has been to a dozen publishers and been rejected by all of them, the editor is going to think there's no way I want this work. Not only that if you whine on Facebook or Twitter, you have no idea who is going to read it.
It would be far better to say that you have done extensive rewrites based on comments given by contest judges, critique partners, a published author or an editor you submitted your work to.
If you have totally rewritten the story, then say that, but don't post all your rejections. Don't whine, think before you write anything that might harm your aspirations.
