It's annoying that most of these reviews are focused on Merriam Webster's usability and not the add-on itself. The add-on works great!

As for Dictionary.com, only word wimps use that--it's frequently inaccurate because it uses non-standard dictionaries. Merriam Webster's site is annoying to browse, but at least you're getting correct definitions. I alternate between using Merriam Webster at work (it's our company's standard) and the Oxford English Dictionary at home (it's a much better resource but uses British spellings. While access isn't free, most library systems subscribe to it and I access it through mine).
