The Netherlands based startup, OpenMargin is building a social network around eReading.

Their service, which launched last week as part of The Next Web Startup Rally, consists of two parts. Firstly, an iPad app allows you to read books and create notes. Secondly, a Web app fosters discussion between users over the notes. See our full story on their launch here.
