I'm very interested in this! The infrastructure needed to aggregate on social graphs not defined in a pre-defined appview (e.g. Bluesky) is expensive. However, taking pre-existing Sill users, where I've already done the aggregation, and combining those together for an "institutional view" would actually be doable in the current architecture. Could maybe whip up a demo?

Yes, and you can control your distribution layer from that node, rather than farming it out to platforms you don't control.
