I'm pretty familiar with this "mistake" and I think wanting to be friends with artists is probably a casual blunder I can't help doing all the time. Art is just how I bond with others and I suspect this is the case with a lot of people.
The caveat is that no matter what avenue of art you are attempting to profit from in some way, you are always competing with other artists.
Case in point I was savagely and in a pretty unsolicited way flat out disregarded as a person to buy from, simply on the basis that he was a working artist. Hurtful as it was to hear I don't hold it against him somehow. My personal opinion is mostly different, I could buy a commission or something from an artist I like. Being an artist doesn't change it for me, but other people don't feel the same way. Maybe even a lot of people, I don't know.
Globalcomix is the prime example of a new site on the block which has a disproportionate number of creators to readers and it shows, standing just about the opposite to Webtoon. But it doesn't seem to be clearly established enough to be known so far, that there are droves of people going "hey, that's the place where I picked up titles x,y,z. This is where I go to find good things to read."
Webcomic sites have a problem as old as the dawn of the internet, a curation problem. Tapas and Webtoons kind of solve this by introducing their own curated titles, allowing the sites to make a name for themselves while not locking out other creators (they just shove us in a corner, instead) I think realistically if you want a comic site with more readers than creators you need curated titles- things you know are well made that will draw people in.
Otherwise I think everything you can do to promote yourself online is pretty much a losing gamble without outside forces lending their support to you.
I don't really come here with the specific intent to find new things to read. I'm picky about what I like and even have a habit of putting off reading what I know is good or would enjoy. But that's strictly a me problem.
If someone wants a review I always give it my time and attention. I'm open to reading anything, not just manga (just mostly manga)
