Especially given the armies of people who cross post any decent content to all networks. I hope that here, due to no monetary benefit and no karma, it is only for the love of sharing. All the good content will make it here, but rather than being a firehouse of crap, the community nature should make the relevant communities more focused.
I still use Facebook for local groups. I think even they realise that niche communities without outrage are where the growth will lie. That’s likely why they are scared of federated networks. It could easily kill them over time.
