Itch.io features literally more than one million games. There are some professional quality ones alongside thousands of unfinished demos and basic school projects, and the feature page can only host so many titles. So it's really easy to miss out on some of the gems out there. Indeed, there are many very good games that very few people play because they get buried extremely quickly in the browser.

Besides, there are many one-off developers alongside others who release good-quality games on a consistent basis.  Of course, you can "follow" the latter, but it seems to me that followership is currently underdeveloped. In fact, very few people notice the "view more games by X" button. 

I know each developer gets a landing page, and I know there are developer logs, but the former are not so easy to find and the latter have the same problem as the game browser. 

I personally would love to have a new section within the browser that allows searches by developers (popular, new & popular, games released, number of ratings/comments, etc), as opposed to just being able to browse games. I think this would allow the people who contribute regularly to make their work more visible and to build actual communities around it.
