Interesting article, and I love reading everyone's thoughts here.
I think I would generally agree with the idea that in any kind of creative space, you have this sort of gravity around trends and styles and everything "looking the same".
I think of music for example. Whenever you talk to someone who doesn't listen to a certain genre of music that you might really love, I think it's common to hear, "Oh it all sounds the same". There are certain conventions and a kind of vocabulary that grows up amongst the practitioners which is what makes it the "genre". These conventions change over time because of technology, economic factors, etc. But I think its necessary for things to "look the same" in a sense.
I see it actually as a kind of encouraging sign, because then it gives us as artists something to react to and potentially differentiate ourselves with.
As far as the financial question, I think the good concept is important, but it's also important to innovate in how we make money. I mean, perfect example all three of the SVS guys, they're all doing all sorts of different and innovative things with their careers. SVS being one piece of their portfolio. I think, unfortunately, we're in an age where it's really rare to be someone who makes their entire living from one creative channel (editorial, children's books, etc). But the good thing is that we have all these means to design our OWN creative path.
Anyway, my two cents!
