We’ve been over this before, but editors are important because they’ll catch your homophone abuse.
Here’s an example from an entry on the Strategic Search Corporation’s Technical Recruiting blog:
Clearly, the last sentence needs insight instead of incite. I know that the two words sound the same, but incite means something very different than insight; the two words aren’t even the same part of speech. Incite is a verb that means to provoke; insight is a noun that means clear understanding.
It’s hard to establish yourself as an expert in anything if you can’t tell the difference between these two words, and it’s especially difficult to establish yourself as an expert in recruiting if your blog demonstrates that you don’t know how important it is to hire a good editor.
