For over 5 weeks I don’t have a blue checkmark on X anymore. The amount of views and likes of my posts has dropped significantly. If you don’t pay, you don’t matter apparently.
I’m curious how this will work on #nostr. My latest posts don’t reach many it seems. Or I’m just sending out bad posts… don’t know what the cause is.
I’m curious about future open source algorithms for Nostr. On X I created selections, so I just directly have the people I want to check out in different tabs.
How far is this development in any client? I don’t seem to have found one yet.
