For me, HF19 is not working so well with regards to voting and voting power. You are giving people who comment on your blog a good % of your vote (i think 100% in many cases!) and getting smacked in voting power because of it.
I've noticed a great reduction in up-votes for comments overall. The bigger players are voting themselves and in their existing circles, the smaller players (less than 500 SP) cannot % their vote and so have to choose who they vote for (attract attention from) with their 10 votes. Can't blame the Whales or Minnows for this though, worrying times imo.
