I just signed up for shelfari which also has the mandatory facebook plugin. I love the idea of sharing books visually with others.
But I've quickly found that shelfari like librarything does not like to import books from exported files from my library programmes, despite claiming that they will.
And I don't have the time to add them manually. Has anyone managed to export their library from a programme, and have either of these programmes import them correctly, or found an online application that works?
