What is the biggest thing preventing your friends from using Nostr?
Inertia, effort, network effects, and lack of understanding of how much better Nostr can be
That about sums it up. I think most of us here don't just enjoy nostr for what it is now but we want to be a part of what it will be.
IMO it really just comes down to fatigue. I know I'm not the only one that bounced around a few of these "decentralized social media" shitcoin projects back in the day. Same as people who don't buy #Bitcoin because they've been inundated with so many scams; folks just have a bit of a firewall up that we have to give them grace for, and help show them how #Nostr is different. nostr:note1tjhpkt3jjpem24wlfuesquyuzgausf4xzzsv60hl2xmf57pq8zzs09tn2n
I would say UX, the maturity of most clients, a bit confusing to understand what’s special with Nostr (concept behind relays NIP’s) if you aren't familiar with the technical aspects. Also big one is the network effect. Another one is that a lot of people keep promoting Bitcoin. I can understand it being a bit off-putting if you aren't into crypto or understand what it is. For people that are into other aspects of life and want to find like-minded people.
Good is the enemy of the great.
