Why would I trust that a relay would hold kind:0 indefinitely? I don't think that's a requirement. Moreover, relay X may have started long after any kind:0 for user xyz was sent, so it may never have that kind:0 for user xyz.

Is it more private to use a kind filter? I don't see why. If the data is available, it's available.

Is it more efficient to use a kind filter? I suppose, but the traffic of metadata messages on the network doesn't seem particularly burdensome compared to the event traffic.

The more-speech use-case is apparently quite a bit different from some other clients. Some clients treat nostr as a kind of twitter replacement. But more-speech uses nostr more as a news channel; a place for longer articles and prolonged threaded discussions.

As such, more-speech does not use the REQ filters to follow users. Rather more-speech gathers every message on the network, and then allows the user to pick and choose which users and topics they wish to follow by separating them into various tabs on the screen.

So, if I want to see all the 'bestofhn' stuff, I can go to that tab. If I want to see 'RobosatsOrderbo' I can go to that tab. Indeed, I have a tab set up for this particular discussion.

>For that you use a kind filter. Get all replaceable events without a "since" and all other content "since" last connection loss - 1day or so. Other clients do it that way and it's certainly more efficient and private.
