Out of curiosity, how would you know that the community is large enough, or committed enough? For example, while Julia has been in development for almost 10 years, a lot of the community has now been around for 5 years. There's about 2,500 Julia packages, with the ability to call C, Fortran, R, Python, Java, etc. All the key community stats based on downloads, website views, videos show a healthy growth every year.

While in absolute numbers, we may be at 20% of R or Python communities, I am always curious to understand what people mean when they say the community is too small. What would be a signal that a particular community is big enough?
