Nostr is where I hang out and post content. But I haven’t completely abandoned all use of other platforms for practical reasons. X is still a good news source, especially for in-the-moment real time events. Some of my family and friends are very active on IG for their work and personal stuff too and so I follow them there. I’m not yet sure what the tipping point is that will get them over here, but that is what I hope happens. A couple of nostr apps are good enough now that it might be feasible.
