People who take the effort to produce original content should not have to be scared of evildoers. First let me congratulate you on being one of those hard working people providing original content to the internet!

Yes, there are risk that people my try to steal your content, but since it's original, it's much easier to check.

Know that the article directories you submit your posts to, require their users to add your signature and credential at the bottom or top of the post. That means that if you encounter a post similar to yours not on your blog without the reference to you, they are stealing content and you can report them.

Another way for you to check them is through "copyscape" (sorry, cannot put links here, just google the word).

I hope this help, keep going with the original posting!
