Commenting used to be more common. Before one of the forks (21? maybe 22) comments were "worth" upvoting, but now because a lot of people only vote on posts that are likely to get good awards comments are not voted on (also only awards worth 2 cents or higher are awarded, anything below that goes back into the reward pool, so most peoples upvotes won't get to that level so it is really a wasted upvote. That has been around for a while. I am not sure how many upvotes I wasted on comments before I realised that). There was a significant drop in commenting and interacting on posts after that. But the pay off was less comment spam. I'm not sure the payoff was worth it though... The fact you are getting comments at all is a good thing, but they are likely to be specific to the community you post in, and people are much more likely to comment on something they have a strong reaction to than art, which is a real shame. Unless you post your art to more arty communities of course. Keep up the good work my friend (and for the record, I like your art!)
