Nope, never heard of the guy. At least I don't remember hearing of him. 
Man I comment a lot and try to put my first reactions in them - kind of writing my first impression of the post or the first thing that comes to my mind after reading a post . 
I joined Steemit in Jan 2018 and poked around for several weeks without making any headway. Wrote a few posts that had only one view - mine. After getting bored with my own blog I started going to other's and found out that like me other people too appreciate that their posts be read and of course it's even better if you let them know that you came and read it. Not a revelation by any means but still makes you appreciate the obvious :-)
