In my case, as long as I will have something to say, I will comment. Just engaging for the sake of being seen out there is not my thing. I don't have too many posts in my feed though, nowadays and that's what I need to improve on my blog. Need some more material to glance through. Totally agree with you that engagement is the best advertising way for one's blog. Only rare cases make themselves known just by posting. Overall I appreciate engagement on Steem as it is far superior of the facebook and instagram one. It is straightforward and that's how I consider it to be.
