Hey everyone! This is Megan from the SEOmoz Help Team. I really like the discussion that's happening here. There are some great points coming from all sides! I thought I'd just chime in with a couple of quick things.
First off, if you're ever seeing any discrepancies with our tools, please PLEASE send your information with examples over to help[at]seomoz.org so we can look in to it. We definitely want to see what's going on and make sure it's not a bug that could potentially be affecting a lot of customers. Secondly, it sounds like everyone is getting a different benefit out of PRO, which is great to see because there are a lot of different tools and it can be hard to focus on all areas at once. The important part is that you feel you are getting some benefit out of your subscription. Learning to get the most out of our tools can be tricky, and we're working on making these benefits more clear. One way is through our new Wednesday Webinars, which is a weekly 30 minute webinar with an in depth focus on an individual tool. We just posted the last 3 recorded sessions today, so check them out if you have time: http://www.seomoz.org/dp/wednesday-webinar. We've also been working hard on creating content for our help hub: http://www.seomoz.org/help. You can watch quick videos on how to use our tools, read about their features, and find out some PRO tips.
I hope this is helpful! Thanks everyone for your contributions.
