A lot of the lack of comment voting I think is due to the price. I know I have gotten to the point where I can vote a comment now but my vote value % has to be over 85% and then I still have to cast a 75% vote to make a 0.02 vote that will not get dusted.
I am hoping in some future hard fork we can see an automatic lowering of the dust vote level when the price is below $0.75 for HIVE, a lowering to $0.010 would be nice then I think the votes on comments would increase during the thin times.
Right now it is just to difficult to justify a lot of comment voting for myself. I can vote on a post and reward the author and also build their and my account, or I can vote on a comment have it dusted out of existence and reward neither the author or myself, and grow neither account. A trade off, as my account grows for me this will become no issue at all. Right now I am up to 3700 HP, and that level of stake only makes for a $0.013 vote at 50% on the vote slider, I need to slide all the way to 75% to reach the dust level of $0.020. (all based on current values and vote mana available)
Haven't really thought about the dust level. I was thinking its connected to the amount of HIVE and not the $ value. If it is 0.02$ then I have been giving out A LOT of dust votes :). I vote on my comments no matter the value ... almost like a worthless twitter like.
I just see that no matter the reason people are here, whether for the money side or the social side, we all want to grow our account. I myself would love to vote on more comments, but I also want to grow my account and not just burn tokens, I don't have enough tokens to burn. But with the price increase, and HBD value approaching the $1.00 level, HIVE being picked up on a few more exchanges, it may not take long before I am finally at a $0.020 vote value at 50% vote slider.
One thing that is nice is I do feel that commenting is picking up some.
Some nice balance between the two of them. Everyone wants to grow their account in financially.
