There two completely different applications that will enhance each other . Tons of stuff you can do on Nostr that can't be done on Fedi and vice versa . Fedi was extremely difficult for me to wrap my head around but ounce I coulda kinda understand it I got extremely bullish. Fedi and Nostr are working towards interoperability. What Bitcoin Did had an episode with Obi about a week ago and that is when I saw the light . I had to watch the video of Obi showing the Fedi OS and talking about it's potential to start to grasp it . This was after I had already done about 12-15 hours of research into Fedi . It was easier for me to wrap my head around Bitcoin and Nostr then it was for me to comprehend Fedi . I still don't have a really thorough understanding of it either . Similar to if someone tried to explain the internet to someone in the mid 80's .
