What got me on NOSTR was actually a search for “decentralized social media”. A community I’m a part of was pushing Farcaster and migrating to it from Discord for support. I was like, “what’s Farcaster”…saw that it was (purported to be) decentralized and I wondered if there were similar social solutions. NOSTR came up…I saw it was Bitcoin based (economy wise) and further said, “why the heck would I go to an ETH based platform if I can be on a BTC one.” …the rest is history!
