I think it is 300 SP, but don't quote me on it. I like it, it means whales can spread out their love to a lot more. Imagine if a whales up-vote is worth $20.. maybe he likes a post or comment, but does not think it is worth a full upvote. Before, the whale would probably ignore it, now he can vote what he thinks it is worth and save that voting power for other "lesser" posts as well.
