At the moment, What I think of allows anyone to post comments on a web page. As a webmaster you can link to the What I think of view of your website. The How it works section shows you how.
Soon you'll be able to restrict access to those comments, so any of your website visitor can leave a comment, but only you can read them. We're working on these dedicated priviledged accounts right now. If you'd like to be notified when we launch this exciting new feature, drop us a line.
