I noticed that in the last step, she separated the words Mail and Chimp with a space. Given that this article is kind of about subtleties making a difference, does that introduce confusion as to whether the company is Mail Chimp or MailChimp? When I look at the text portions of the page, I see it referred to both ways (ex: in the page title and left sidebar). On the MailChimp site itself, it's without the space. So, I assume that's correct.
So, could the logo confuse the branding? Or is it unimportant?
