Despite the non-incentive at all for voting comments due to the "weird" rewarding curve algorithm, commenting and voting valued comments of other people are becoming more and more important lately.
We are a Social and Community Blockchain so, if we want to make it different from the old Steem blockchain we should look for a solution in order to encourage and reinforce commenting as the main engagement aspect of our HIVE blockchain.
My opinion is that we MUST relax this curve in order to make it more linear as it was 8 months ago... we have controlled the bid-bots and others abusers so we can get back to a more social strategy IMO.
In the meantime, I think commenting and voting comments keep being ESSENTIAL for the long-term run for anyone willing to succeed in this blockchain and more specially during these days on which the rewarding curve presents the following scenario according to https://hive-now.com/ :

You don't lose so much by upvoting comments but a little of HIVE POWER, instead what you get is an INCREASE on your ENGAGEMENT DEGREE THAT WILL PAY-OFF YOU LATER ON!!!!
Just for you to know, and as a curiosity, a few months ago this "crossing" was placed somewhere in the infinite:
