I don't know about you guys but I personally enjoy giving out a new address for every receiving transaction...so fresh and clean. You also reveal less information about yourself. It's like using a seatbelt, yes you can drive without it but why not take advantage of it?
Exactly. That obsession with single address is so noobish, I remember when I've was first using the wallet was so pissed-off that change was not sent back to sending address, was even trying hard to find out if Bitcoin-QT can be set to do that. Even payed transaction fee to send it all back manually to vanity addy from time to time. Now I understand that default behaviour should not be allowed to be changed, but it took time for me to figure that out.
We seem to be trained to use only one address for some reason, maybe because we don't change street, email addresses, or bank accounts so often, or because it is such a large string. It takes time to get used to the fact that's just another key, used now and never again. I guess every new Bitcoin noob has to learn that himself.
