I'd like to add that one of the issue small creators can have (and I mean any type - even people like me who have zero ambition to make money and not a extremely huge ambition as an artist in general), is that we may be small, but we are numerous AND we make, as a community, Tapas' model work.
How many times did I read things like 'Tapas, oh no, it's not free, I can't pay' or 'there is also Tapas if you have money to read' etc. I, as well as a lot of other creators (small or big, but small are more numerous and may have more time), am there in other comic-related places, non-comic related places, other languages places etc, telling people that not all Tapas is paying, that there are ways to read the paying comics without a credit card if we're patient etc.
But still, the general idea in people's mind is that they can't read free on Tapas, so they don't even come.
I may only have a very small, non professional comic, but I can (and do) bring people to Tapas by educating people about Tapas. My role is very small because I'm very introverted, but someone with a good online presence could do lots more, for part irrespective of the size or quality of their comic/novel.
Obviously, having small creators feeling not compensated for their advertising role (among other things) is not conducive to enthusiasm for advertising more... Which is bad for every single creator, big or small.
The question should be 'how and on what criteria can we help small comics be visible when there are so many of them', not 'does it really worth doing it when there are more popular comics out there that we could profit from'. Small comics are a part of a healthy Tapas system. Each only does a small part of the job, but as a whole we are very important.
I'm sure everyone know that, but I think it's easy to forget when looking at a few bigger titles, comparing, etc. We should not forget there are different roles to play to make the system work, and that every role filled should bring a minimum of incentive.
