No, stars don’t matter.
I’m mostly late to the party at these things like stars on GitHub but as far as I understand it, it’s nothing more than a like button. Please correct me if I’m wrong.
When I consider a library then I look on the activity in the repo. Are there issues? If, are there conversions going on and how old are the issues? Are there PRs? How old and how long did it take to merge if merged at all (seen half year old PRs that didn’t mergen despite no issues)
That gives you a feeling what’s going on there and what chances are things get fixed when something is coming up.
