On the Caveat Emptor (“Let the buyer beware”) side of things, I look at other metrics well before I rely on stars.

How many contributors does it have? How many active forks? How many pull requests? How many issues are open and how many get solved and how often and how lively are the discussions? When was the last merge? How active is the maintainer?

Stars might as well be facebook likes imo: when used as intended, they didn’t say much more than “this is what the majority of people like” (surprise, I’m on lemmy bc I have other priorities than what’s popular), now they mean nothing at all.
