I’m not trying to demean your work, but an idea isn’t copyrightable (and if you don’t believe me, the government says so). Truth be told, original ideas don’t exist, and even if your idea somehow defied that rule, it still wouldn’t matter if someone stole it.
Why? Because as anyone who has tried to write a novel before knows, an idea is just an idea. It’s the seed of a novel, but it’s just that. Even if someone stole your completely original, totally brilliant idea, they’d still have to write a book to match up to that brilliance. And hell, maybe they would. Maybe they’d write it better than you did. But their book wouldn’t plagiarize your idea any more than Richelle Mead plagiarized Stephanie Meyers, or Meyers plagiarized Anne Rice, or Rice plagiarized Bram Stoker.
You see, they all wrote books based on a somewhat similar concept, but they wrote their own novels. They each wrote something different, because they each had a different take on a similar idea.
Anyone who has taken a writing class ever knows this very well: if you give a room full of students the same idea to write about, they will all write something different. Will there be similarities? Sure. But does that mean they somehow stole from each other? Does that mean their work shouldn’t be considered their work, or that it shouldn’t be considered original? Of course not.
The thing is, even if someone liked your pitch so much that they decided they wanted to write a book just like it, it wouldn’t matter. You’re already ahead of the game: you have a completed manuscript ready for pitching and they’re just scraping together ideas for a rough draft. And whatever they come up with based off of those 140 characters, I promise you, will be verydifferent from whatever you wrote. And, there’s still the whole matter of getting it published, which, as you already know, isn’t so easy. So.
If you have to worry about something, worry about having your writing stolen if you post online. Worry about someone copying your blog posts and republishing them under their own name. Worry about people pirating your work and selling it for a profit.
But as for someone stealing your ideas? Don’t waste your energy.”
