I wish more people just wanted to create and post for the pure joy of creating and sharing. I feel bad when I see people eating their hearts out over the metrics. I agree that stuff's important if you're making a go of it and ultimately want to conquer the world (or at least, a niche market) with your comics, but too many people seem to define their level of talent and personal success by how many people like their stuff. And besides, online publishing is a mug's game in the respect that it's just DARN hard to make a yearly, dependable, living wage at it compared to almost anything else you could do in life.
If, then, the only logical reason to do it is for love since logically it is a losing proposition compared to most other jobs, it's sad to me that people are either not doing it for love, or are allowing their joy to be crushed by the business aspect.
You could literally have made the best thing ever and no one might ever see it (or understand it). If you're purely looking at things from a marketing angle, that "best thing" would be worthless because it didn't get noticed. I would rather see a creator who had made something precious be full of joy and pride that they made it, and grateful that they had the time and the means to fulfill their dream.
tl;dr I don't think it's foolish at all to feel like your work has intrinsic worth, and for your main goal to just keep doing what you love whether anyone else sees or not.
