I was a big proponent of this plugin. But, when I discovered that the plugin was acquired by that guy from Awesome Motive I knew it was time to start looking for another SEO plugin, as he already ruined a pretty popular Google Analytics plugin in the past. My suspicions have been confirmed. The moral of the story is that acquisitions are usually a bad sign for a product because for the new owner the tool is simply a new additional way to make money and expand his portfolio. Now I use The SEO Framework in all the sites I manage.
