Interesting! I'm sure I knew about this, but it definitely is something that's slipped my mind.. I do love upvoting the comments I get/see, and happy to do them at 80%-100% because I usually don't get to use my VP much nowadays anyway, due to lack of time curating. I guess if I'm not keen on giving someone a 80%-100% upvote on their comment, then I'm better off going to their page and upvoting their post instead. Thanks @slobberchops and nice to see how much you've dived into Steemit :)
