Errors cropping up

With some of my posts, I've noticed that I've cut and paste sections of text from one part of a post to another. I haven't been able to figure out how I'm managing to do this accidentally, but I think I've caught and fixed it every time it's happened. However, if you're reading this blog and notice an error like this somewhere, please let me know so that I can fix it. I try to read through my blog entries before I post them, but sometimes these errors have actually happened as I read through the posts.
