We should limit voting, and limit based on IP. If we go via email, then anyone wishing extra votes merely needs to use mailinator.com (and its dozens of alternate domain names, to say nothing of competitors providing similar services) to vote as many times as they want. If we care about fraud, then it would be a very troublesome task to filter out all those ways to fraudulently vote; if we don't care about fraud, then email confirms are just a burden on honest users.
I don't know about other people, but for me it takes less time to change IP addresses than to sign up for a mail account. dhclient -r dsl0 && dhclient dsl0 vs. fill in a form on a webpage. --Max
