Fixing the data silo problem is a huge feature of Nostr. As I try more front ends and micro apps for my Nostr experience, the ability to move my identity effortlessly to other software, bringing all my data with me in the process, is amazing.
Rather than a new web property needing to be setup and filled with my information, it is there, and I can just start using it. Nostr may have a high bar for entry, but once you get it things become a lot easier! Not having to worry about a thousand logins is a gamechanger!
