I love the site. Very well done! It wouldn't surprise me if it starts showing up in some undergrad CS lectures.

The thing about the stars, though: some of us fear that a utility site for our work, GitHub, is getting enshitified into a social media platform. So for those of us in that camp, the stars system is unwelcome all by itself, and catering to it is the opposite of what we want to encourage.

Your desire for feeling the work is appreciated is definitely reasonable though. I hope how much I like it comes across loud and clear :)
