The image shows the contents of the "ub" tab. This is a tab that I created in order to display any message sent by me, or that somehow references me. You can create many such tabs in order to track individuals, groups of individuals, or topic threads.
The display shows all the events, from all the relays I listen to, that meet the criteria of the "ub" tab For example, the message at the bottom ("Yes, entirely tangential...") came in on relay.nostriches.org, relay.damus.io, filter.nostr.wine, and eden.nostr.land.
More-speech is a client in that it displays messages to the user. But more-speech is also something of a relay in that it reads and stores all events that come into it from all the relays it listens to. Indeed the "all" tab shows all those messages.
That's a _lot_ of messages, but it's useful for querying purposes. You can go to the "all" tab and search for "black hole" if you like, and find all the messages that mention those words.
