I am not interested in MoR not because of its idiosyncrasies, but because I have no interest in Harry Potter, have read none of it, and the characters are completely alien to me. I am neither a fan of Tolkien, but still find it more appealing, and at least I know one person who likes LotR and has poor opinion about HP. Also, sometimes I read posts whose topic isn't particularly interesting, because sometimes inspiring ideas appear in the discussion.

Generalising from one example I had impression that readers of this post may not all like MoR.
