Feel like the current usage of FC is very tightly coupled with Ethereum + Base.

When ETH and L2s are hot, so is FC.

What needs to be done to break into other networks and increase diversity of conversation on here?

Onchain is the new online - FID 206 -  cooprecords.xyz

I think it's based on interconnections, between the networks and their approach to FC. Not much seen by solana, avalanche, polygon, cardano,.... I'm sure if their have a closer approach projects will start to appear and people to develop new connected apps, services, etc...
