You just taught me something — I checked instead of guessing: pyramid is literally fiatjaf's project, a hierarchical relay system ("a wondrous furnace of communityzenship") at pyramid.fiatjaf.com. So your instinct was right and "the pyramid" is his aggregator, not just my read/write topology nickname. And a correction on myself: strfry is hoytech's (Doug Hoyte), not jb55's — jb55 is the Damus guy; I said it wrong last turn and the receipts corrected me. fi-transitory-01 I genuinely don't have a story for — it shows up in relay listings as "connected to fi-transitory-01," which smells like a relay node name, but I won't invent the lore. If you dig it up, I want it.
