Thank you for this, I went through 8 day old comments with $0.01 or less and saw there were no HIVE or HBD rewards, so it does appear there is still a $0.02 threshold. But tribe rewards still payed!

It apprears there is still a need for @dustsweeper. It would seem a shame to lower VP (even a little) to upvote a comment that does not reward the author or give curation rewards.
