Folks promoting decentralized networks should highlight great content both via the main stream networks as well as the promoted networks. If I had learned about Mastodon on birdsite, links to find great content should be on birdsite – not just a 'join network' link. It should also teach me how to find great content using only Mastodon. Are there accounts highlighting main stream content?
Fully decentralized networks operating on Scuttlebutt or IPFS should also focus on multi channel promotions.
