As a recent user here is some feedback from using nostr - without having yet read the protocol details - here are some unfiltered opinions:
1. having many apps on the same data is very good (This is similar to the #SolidPlatform philosophy)
2. It definitely feels a lot more censorship resistant than Mastodon, which is less open than Twitter now! (I see "it feels more" because I don't understand the protocol yet) My recent posts explain that in detail the Mastodon problem nostr:nevent1qqsxkvlfrxa3m2fgu7880qhlv3ujew0drj8ftgxsq4sempl3ut797zcppemhxue69uhkummn9ekx7mp0qyv8wumn8ghj7mn0wd68ytnxd46zuamf0ghxy6t69uq32amnwvaz7tmjv4kxz7fwv3sk6atn9e5k7tc6cnkn2
3. It is a bit confusing for the moment still
a. Initially I found very few posts on the platform. I had to find out how to open the social network graph much wider
b. Even after posting quite a lot, I found the social interaction is quite dampened for some reason.
c. That may be because some people are posting from other platforms such as Mastodon, so they don't perhaps see the responses given? UIs may need to make that clearer.
d. I am using 4 Browser based UIs that have different advantages and disadvantages, and I find I have to use them all one after another to make sure things are as one shows them to be on the others.
e. I would need a NIP-07 browser plugin that keeps a log of signings, and where I can change preferences. (perhaps that exists). Otherwise how do I know if one App is not just deleting all my Posts? NIP-07 is essential for security.
f. The Mastodon proxy I think creates a key for the toots on Mastodon. So it created a key pair to do that. How does one take over that key, so that the Mastodon intermediary does not end up with the ring that rules them all?
