IMO some things that would help tremendously and that would be good to prioritize, ways:
* Of having a persistent identifier that is decoupled from your server. Whether this looks like the current #VC and #DID proposals is less important than that the decoupling takes place.
* Of sharing and pooling moderation, load, storage, privacy, and security resources (see my previous discussion of #APAF/#ActivityPubApplicationFirewall or #APRL).
