I'm not quite sure, but... lately I seem to experience this:
I receive 1 exp for every one or two ++ one of my nodes get.

Well, my math isn't really great so I can not check if this is due to a high or low $NORM but I think it is pretty rude to keep gaining exp like a mad thing because of a small reply node to a small root node.

Am I the only one experiencing this? If not, then what's the reason of it?

Just wondering $0.02.

Besides that, my code is untested unless stated otherwise.
One more: please review the article about regular expressions (do's and don'ts) I'm working on.
