Not really. Automattic does a great job with Wordpress and keeping services online, no judgment of them.
For a company as large and successful as Amazon to launch a product on a default blog template under their domain? That's like launching a product on Blogspot, with that 'circles and dots' theme or whatever: it looks unprofessional.
Agreed, at first I just chalked it up to this be a "rogue" blog by some members of the team, but this page is the only "official" page I can find on the product. The favicon is even Wordpress...
