a general offer to no specific person should require confirmation from both people to each other.

an offer to one person will only require confirmation from the offeree, unles the offerer revokes it, first.

This is a pretty solid rule IMO ... saying "i'm offering up to z $ 1:1 on x against y, plz state amount and consider it booked" doesn't seem like a valid offer to me. No one is going to book a bet against any random poster. That would be really different if a certain person offers to a certain other person.
