I think we should have personal relays that periodically connect to any other relays to gather notes (and other things) from the people you follow. Then your client connects to your relay to get a large dump of updates. This should be easier on your phone, for one. The other benefit is you being able to keep archived backups of things you're interested in (bookmarks, etc). It can also run local AI systems to moderate content before showing it to you. You can configure this AI to create a personalized feed and block things of your choice. I think it can help solve the human moderation problem.
