Doesn't matter if my upvote is dust. I will upvote anything I think are good to upvote and resteem those that I feel should be shared to my followers. :D 0.01 will accumulate in time. :)
I upvote posts more often than comments. Unless it is one of those that are in my contest entries. Hehe.
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.
Yeah. It's good you're sharing it too. 👍
