If you want more grammar ninja moves than my daily “Writing Glitch” posts provide, or if you want to learn about other aspects of writing fiction, here are a few blogs you should look at.
The blogger at Terribly Write gleans examples of writing-mechanics errors from Yahoo! articles and other sources. The posts are short and concise, and the types of errors are listed in categories for your convenience. (More than eight hundred examples of apostrophe misuse!) Says the blogger, “You won’t find all the rules of grammar, punctuation, and spelling here. Just practical, pragmatic, and prescriptive tips for writing for the Web.”
Then there’s Quintessential Editor. As the blogger says on his Welcome page, he provides “writing tips every day, for everyday writers. You will find information regarding writing, editing, proofreading, and other miscellaneous tomfoolery.” Also, he’s funny and entertaining.
Janice Hardy’s Fiction University. The tagline for this blog is “Taking Your Fiction to the Next Level.” You won’t find the mechanics of writing (grammar and punctuation and stuff) discussed here. What you will find is a large collection of resources for story development: brainstorming, worldbuilding, plot structure, characterization… voice and style and when it’s good to use adverbs. There are also articles on what to do after you’ve written your novel/short story.
Dan Koboldt’s Science in Sci-Fi, Fact in Fantasy series. If you write speculative fiction of any flavor, you need this. For each post, Mr. Koboldt has an expert in the topic share the things authors need to know about it. The articles are overly detailed, but they hit the highlights, and they’re more than enough to point you in the right direction for further research. These posts aren’t just for SF/F writers, either; any author can benefit getting the facts right in their work of fiction.
