As you say, its not so cut and dry. Gunicorn has only had a mailing list since about May. Most of our dev work is based in IRC or via the GitHub issues tracker. The three committers, @benoitc, @tilgovi, and @davisp have a combined 1709 twitter followers. There are also 479 watchers and 64 forks of the main development repo on GitHub. Bottom line, numbers like this don't really mean much. In the end, people should investigate any project they think is a candidate and make a decision based on their specific criteria rather than try and use some proxy metric to make the decision.
