Awesome product for keeping track of vulnerabilities and updates with your site. I have used it since it first came out and can't say enough good things about it. These guys have created a really top-notch product.
My only complaint (not reflected in my 5-star rating, mind you) is that their paid version is just too expensive. I manage too many blogs to pay for each one, but I certainly would if the cost were less. In the meantime I'll stick with the free one, and hope that enterprises that can afford to fund the full version will continue to allow a free version to exist. Should they ever lower their paid version to a price that is appropriate for web developers and webmasters of multiple independent blogs, I will be happy to join the paid ranks.
Great job, folks!
