Here are a few more good links since my last post.
An amusing grammar lesson. Don't click if language offends you.
Mostly of interest for mystery writers, an article for New Orleans LEOs on interviewing techniques from BJ Bourg, a writer I admire.
This was added to my last post in the comments, but I'll put it here in case you didn't click on those.
A simpler website that just counts repetitious words is here.
And a place to buy fancy software that might be even more helpful, but you have to watch your language here. Page down for an amusing pledge that prevents me from buying this.
Here's a somewhat pessimistic look at promotion with some interesting comments. This, BTW, is a blog worth following.
Get your flash fiction news (contains contest and market listings) here! And visit the companion blog for more flash fiction info.
That's what I gathered. Hope some of it interests or helps you!
