> A question for all open-source people, how do you measure these different sources of traction as I also got nice discussions under the posts.

The only measure I've found that's useful is actual engagement: real people asking real questions about the project, bug reports, help requests, that sort of thing. Tangible evidence that the project is being used.

I've found generally that things like upvotes, github stars, etc., aren't actually very good indicators of traction. They're very crude and have a very large margin of error.
