Another topic which is somehow related to give feedback/appreciation
I recognized this behaviour in a lot of my repos and after viewing the profile of those users it looks like a scheme. So
Why do people fork repositorys on github instead of starring them?
Fork a repo:
You fork a repo if you want to make changes to the original codebase and use the fork or create a pull request.
Star a repo:
You star a repo if you like it. It’s similar to upvote on the forum or likes on facebook, youtube, … and gives the developer kind of credit for his work.
