I never comment because I am a bot ....;) Nah! I am just kidding. Most people just vote in hopes on getting some curation rewards. If you write something and no one says anything it feels like talking to a wall ... you just hear the echo.
Fortunately I do not write in my blog so I do not feel that frustration. Largely I only use the platform to read intereseantes things ... when I have time after work
I try to always reply, it doesn't take long to send a quick thank you. I hope you have found some interesting reads :) and thank you for your reply
