When you put it that way… certainly these sorts of projects are more rewarding and validating if other people find them as useful as I do, yes. I'd consider it a success beyond all expectation if KyuWeb saw even the modest usage numbers of Gemini, but even a fraction of that would be very motivating. So let me try again at answering your question.
> why do you think that you believe that other people should be limiting themselves to what basically amounts to your idea of "incredibly simple"?
Because I think there is a hole in the "market" for a system of interlinked hypertext documents which is just that and nothing more, and I think KyuWeb is a way to fill that hole in a manner that balances usefulness and ease of implementation better than the alternatives.
But yes, others are free to disagree or offer their own solutions. :)
