I think we will see communities across instances growing. I notice there are about five synth communities or so according to browse.feddit.de with the largest being this one and the one over at midwest.social. On desktop, I can see stats about the communities, but I'm not sure if mobile goes into much detail. Regardless, participation and just being here are what matters. Even if /r/synthesizers users do not find us, we already have a good thing going in my opinion.
