For anyone who still thinks you need to ration your votes because you have a limit, that is no longer the case.
So you can vote with wild abandon. OK, well, don't vote for things you really don't give a hoot about. But if there's any chance you might be interested in a book (if you had enough money at the time it became available), or if you want to help someone else who desperately wants something, then go ahead and vote for it. You've got nothing to lose.
