I don't think it's too much to expect readers to do a little googling about a company they aren't familiar with.

This was an excellent article whether or not you know anything about moz.com, and finding out is easily remedied.

Wow, barely three weeks into your new account and you already want to dictate what gets posted.

Regardless, what Moz does is about as far away from my day-to-day work (or even my interest) as you can get, and even I know what their business is. Doesn't matter, plenty of postings here are about companies I've never heard of, so I go look them up. Takes less time than it took you to type your comment.

Lastly, what Moz does has little bearing on the content of the article. They could make oil filters for cars and the content would stand on its own (well, mostly).

Is there posting guidelines that prohibit posting things like this?

Otherwise, enough people voted for this submission to be relevant.
