Good morning! I think that the decreased number of upvotes is due to changes after HF19. People can only make about 10 full-power upvotes in 24 hours, which makes them much more selective than before in choosing posts deserving their upvotes. Or voting with less than full voting power (if they have at least 500 SteemPower, that is). I’ve now changed from voting with full power to voting with 15%–20%, in order to give more upvotes in one day.
Good morning! A few people have indeed mentioned this. It makes me wonder how many of my votes previously came from smaller accounts who don't have the slider yet. I've also changed my voting percentage so I can still upvote all that I want. Thank you for your input!
