Yeah ghost towns are an issue, but the fact that the sub exists means that there is atleast one more imterested person there. Ive been poting in the taskmaster sub now to try to get some traction and atleast 2 or 3 people are there and I'm hoping it can grow. I suggest the same, shout in the town square to make sure there isnt a drunkard passed out who you didnt miss.

But that also means we don’t have enough users or content yet.

This may very well be the case currently, but it isn't necessarily the indicator for such. A critical mass of people using the fediverse can still result in smaller communities due to the local-first nature of the space. If we had 10 million users interested in a given subject, but they're spread among 2000 communities called 'interest' spanning 2000 servers, that's not actually a problem. That's a situation where the global ecosystem is rich and lively, but people are still seeing the same names over and over again in their little interest pocket.
