I didn't mean to be harsh in my initial reply, and questions are a way to avoid being harsh. If you see yourself often using this HN account to talk about seomoz I suggest putting it in your HN profile, that way if you don't disclose in a future comment, the next person may just make a note. In fact I thought of doing that but didn't, partly because I was curious whether you still worked for Moz, because in most places, like your blog, it just says "Distilled".

And your comment is pretty neutral on the face of it, but if you read between the lines it's a defense of seomoz. That's why I wondered if you were connected to them, since you left the first comment it seemed that you may have received a google alert.

Apology accepted.
