No, voting's already been cut way down as a source of XP. The idea is that you receive XP from OTHER PEOPLE voting on your writeups, not from voting yourself.
If you make no writeups, but simply vote out every day under the new system, you will eventually reach Monk. It won't be fast, but you'll eventually make Monk. And there you will sit. Statistically, yes, you'll continue to gain XP from voting and logging in; but it would take months to reach Friar.
The idea of this is not to encourage what someone called "good voting behavior". It's to encourage contributions to PerlMonks. You can't gain XP unless other people vote for your writeups on a consistent basis. The better your average reputation, the faster your growth. So although it's absolutely crucial that people continue to vote, it won't directly do much for their XP levels.
We want you to vote for root-level nodes. And for replies. And we want you to vote on the deep, far reaches of the threads. But we want you to vote based on what you think of the node, not on what reward you will get. We don't want to reward good voting behavior. We want to make voting essential to good community behavior.
