Thanks for pointing that out. I have a really bad habit of skipping words when I'm writing, and sometimes my brain causes me to miss them again when giving a post a look over. But yeah, I indeeded the Hulk.
The number one editing trick to catch these sorts of things is to verbally read your post out loud. When reading in your head, your brain autocorrects things without you realizing and you're bound to miss mistakes. Reading out loud allows you to hear each word and syllable so you can notice when something doesn't sound correct, and then can fix it accordingly. I can confidently say that doing that will catch 99% of all errors made during the writing process.
