This is an attitude you run across all the time, in nearly every creative field. On Tapastic, it's mainly focused on getting subscribers, because that's an integral part of the site, but you see it elsewhere in other forms - all those people asking talented artists "what's the trick?" as if there's some cheat-code to artistic skill other than "study and practise" applied over a long, long time - or all those people asking successful indie game-devs for the trick to how to "make it", as if there's some secret godmode to being an overnight success.^
No one likes to hear that there is no magic trick or cheat-code to getting good and/or popular - the same way no one likes to hear that most diets aren't gonna make you lost x pounds in y weeks. We like things to be easy and involve a minimum of effort, even though most things are hard and involve a lot of blood, sweat and tears. If there is a magic trick, we can blame our failure on our ignorance of that magic trick, instead of looking hard at our own efforts and trying to see what we could be doing better.
I have a big bunch of subscribers, and I appreciate every single one of them - but I'd still be drawing my comic even if I only had 10 subscribers. As long as someone, somewhere, cares enough about the story I'm telling to want to read it, I'll keep going. Heck, I'd probably keep going even if NO ONE was reading it, because I'm a storytelling junkie. I just might not be doing it at the same pace.
Make no mistake - I've days when I wonder what it's all for, and feel useless because I've posted something on, say, Tumblr, and gotten only crickets chirping in response, and sometimes I still do. It's terribly discouraging, because one of the purposes of visual art is, well, that someone looks at the thing - but I've just kept on going anyway.
It's paid off, but it's taken years. Not everyone wants to put in that kind of time and effort.
^) "Overnight success" is a terrible term, because 99% of everyone who becomes an "overnight success" have been working at it steadily for years, you just haven't been watching them.
