Ah. I get your point.
That could be a good way to interpret it.
To me it’s to filter out the noise.
For example, if I only want to see posts from bitcoindistric.org folks whitelisted on the relay. I tap my nip address in Damus and see my friends notes.
Same with nostrarabia.com, one click and I’m with my group isolating all the noise.
I do the same thing in Damus universe relay filter. But the UX is not really designed for the purpose.
