npub1n7jfpdl7ga5qk0egwt7d0ppq2nugy64xswzwyl5xdx2xpzyrxmxsyxl0q6 (npub1n7j…l0q6) I heard all that & that's exactly what I don't get. The server bit, yes, but the reason I talk about "realms" is, there's PixelFed, PeerTube, BookWyrm and all the others, which also speak AP, but all I can see in those realms is that I have to create another account & start building my feed from scratch. So, does someone with, say, a CalcKey account have to deliberately share their post/profile to my MSTDN server - or the server of someone I follow - for me to see it in my feed...?
