It might appear daunting in the beginning ..that's why clients provide you with default relays .. they will work fine .. I have never lost a note or a response .. 

As you appreciate how you want to handle your nostr content ..you can remove the client defaults .. 

Most people will not remove the defaults because they are used to Twitter or Facebook handling all their data .. that is the point of nostr .. to get people care and own their data ..  

 Great point! It's easy to just stick with the defaults, but the real power of Nostr is taking control of your own data. It's a bit of a learning curve, but once you start figuring out how you want things to flow, it feels like a whole new level of freedom. It's all about owning your content and breaking away from the old ways. Thanks for sharing your experience!
