If the number of stars are in the thousands, tens of thousands, or hundreds of thousands, that might correlate with a serious project. But that should be visible by real, costly activity such as issues, PRs, discussion and activity.
It is the meaning of having dozens or hundreds of stars that is undermined by the practice described at the linked post.
That said, I believe the core problem is that GitHub belongs to Microsoft, and so it will still go more towards operating like a social network than not - i.e. engagement matters. It will still take a good will to get rid of Social Network Disease at scale.
There are much better ways of finding those who have good taste.
Two projects could look exactly the same from visible metrics, and one is complete shell and the other a great project.
But they choose not to publish it.
And those same private signals more effectively spot the signal-rich stargazers than PageRank.
The fake accounts often star my old repos to look like real users. They are usually very sketchy if you think for a minute, for example starring 5,000 projects in a month and no other GitHub activity. One time I found a GitHub Sponsor ring, which must be a money laundering / stolen credit cards thing?
Even 10 years ago most VCs we spoke to had wisened up and discarded Github stars as a vanity metric.
GitHub should also introduce a way to bookmark a repo, additional to the existing options of sponsor/watch/fork/star-ing it.
one VC told me, you'll get more funding and upvotes if u don't put "india" in your username.
Founders need the ability to get traction, so if a VC gets a pitch and the project's repo has 0 stars, that's a strong signal that this specific team is just not able to put themselves out there, or that what they're making doesn't resonate with anyone.
When I mentioned that a small feature I shared got 3k views when I just mentioned it on Reddit, then investors' ears perked right up and I bet you're thinking "I wonder what that is, I'd like to see that!" People like to see things that are popular.
By the way, congrats on 200 stars on your project, I think that is definitely a solid indicator of interest and quality, and I doubt investors would ignore it.
I think VCs just know that there are no reliable systems, so they go with whatever's used.
