I am looking for a plugin that mimics or provides the features as in here Marginalia. Its a elegant way to mimic the age old way of annoting a book on a web. from the little knowledge that I have about plugins and wordpress. I assume integration of the feature is possible with a wordpress blog.
I would like your help to understand if there is an existing plugin with similar features or can someone provide me pointers or collaborate to build one as I am not too conversant with php and mysql.
Any information in this regards would be highly appreciated
