I don't think its so much about adding interests as it is offering random but related articles to what someone views. Not everyone always checks the related articles section- and that section is not always very comprehensive. It'd be a good start to use that section though, and compensate by eliminating pages you've already visited.

I really like your idea, although the implementation still needs the actual recommendation engine. Wikipedia could really benefit from more related articles being listed/organized.
