I think HF19 has changed the way people vote. Smaller accounts that haven't achieved 500SP can only vote 15 times a day or their vote power will be sapped and won't recover. This has made quite a few accounts a bit more stingy on upvoting versus pre HF19. I find my posts receiving the same number of comments, but fewer upvotes.
The threshold for the sliding scale needs to be lowered to accounts with 200SP to remedy the situation.
This is a point that I have never considered! I see that you are over the 500SP marker. Well done!
Thanks @kus-knee. It's nice to have quality mentors like yourself in the community.
