There is no problem if the post or comment exceeds 0.02 because by reaching the threshold there is a big chance that it will be paid out. I am not discounting the value of your vote and my recommendation here is instead of leaving a 0.01 value on a wonderful comment why not go to their blog and upvote something that you like and hopefully it is more than 0.02 cents so the person can be rewarded.

In the end it is your choice what you want to do with your VP. We are merely trying to inform people because I didn't know this.
