Here at TD, we often post and read about the issues that type designers encounter at font stores. This implies that could exist a font store that is better both for customers and type designers and still make money for owners.
The hope is that by presenting our ideas, we can define a reasonable (optimal and sustainable) model.
Not only our wishes but also important functioning questions. For example, if the hyperproduction/quality are issues, there should be criteria or jury or a limited number of additions per year, etc. In the case of a jury, those people spending time carefully reviewing entries should be paid, maybe anonymous or temporary members. Also, which ideas are implemented (upvoting or decision-making board) etc.
The market is oversaturated, but still, there might be a space for a font store that delivers the best products on the market, educate users on what to look for and why it is important, and communicate that "buying on this store you are directly supporting type designers".
Because the model should be "optimal and sustainable" (and if turns out that such a model could be defined) maybe TypeDrawers would be interested in opening such a store. The commission rate should cover the salaries of the employed people, marketing costs as well as a stable support for the TD forum.
