I think ultimately, the most important thing is to define what a individual creator's goal is before giving advice.
Do they want to get lots of views and cultivate a following? Do they want to create x-thing for their own self improvement and simply have it available to the public for more accessible feedback?
Personally, after I graduated college, anything I post online I welcome any sort of response. Right now it is largely about trying to grab people's attention, since I want to ultimately monetize it. But before I was aware of the plethora of sharing networks online, I was pretty happy just making things to entertain myself.
I think back to the first graphic novel I ever completed. It was created years ago during college, way before I even considered sharing a comic on the internet. I think maybe only 10 or fewer people have actually read the whole thing and I never got any real feedback on it. But I enjoyed making it, the whole process from scripting, drawing, photo-editing, graphic-designing, printing, and binding 3 copies into an actual book by hand. I was practicing, putting my skills to work. And I was happy with it. I even ended up using it as part of my senior project/thesis.
And even the comics I made in high school, the only person I really shared them with were my dad. They stood as my own twisted diary entries, blending real jokes and funny situations from my classmates with completely invented fantasies, fun stuff I wish could happen, often parroting the wacky shenanigans of the cartoons I watched. So while my dad's reactions were the cherry on top, I was satisfied that I could make myself laugh with my own imagination and recollections.
(If you can't tell I'm an only child lol.)
