I've subscribed to SEOMoz for just over a month as part of looking at how we should be working on SEO specifically at Mandalorian[1], and also to evaluate how other similar companies use SEO. After a couple of days with the tools I realised that this actually gave us a whole load of much more useful information to help with general marketing exercises.

I might have joined for the SEO, but am most definitely staying for the marketing. I wish Rand and team the greatest success with Moz.
