*openmargin is an e-publisher devoted to creating mini-social networks around marginalia in its books. Much like vialogues is to video, *openmargin is to the e-book. It’s a similar concept to former EdLab review features like Bookhunch and NowComment in its devotion to community around content, but its style and niche offerings set it apart in the genre.
One of the coolest features in *openmargin is the cool (again, Vialogues-esque) comment timeline which allows one to mouse over profile pictures of users and see the points at which they comment in the book. A click will show you their comments. On the front page, a similar thing happens with book covers. Mousing over will show a random selection of participating users and a click will show the book on their profile page. It’s overall a very slick website with adorable Dutch touches (Dutches).
