She takes away from all the Penny/Sheldon shippers true love. ...though I don't know why anyone thinks Sheldon would ever go for Penny. If he even liked the idea of sex. It makes no sense, but who expects sense from fandom? ...or maybe it takes away from the Leonard/Sheldon shippers. Are there any Leonard/Sheldon shippers? You'd think there would be. They'd hate female romantic interests who got in the way. ...it's possible I'm a bit jaded.

I don't know, my only problem with the relationship would have been that I feel Sheldon is extremely asexual, but they've managed to keep him perfectly IC in his completely sexless relationship, so instead I enjoy having a girl nerd on the show.
