Yes, you can see the value of the upvote button, I've noticed that... Steemd.com and I've noticed that you upvoted your own reply to my post, yet haven't upvoted my post.
In fact, looking at all the upvotes you make, they are only on your own comments - no one else gets an upvote from you.
If you then take a look at what your upvote is worth to you - $0.01 - and then take a look at what I gave out when I upvoted comments on this blog - typically $1.05 - which would you rather have on your comment?
Unfortunately, even if you change it all now, you're not getting anything.
Harsh but fair, I think.
