To take off you need an initial mass, to attract such mass you need something juicy out of the box. Nostr is a wonderful idea, but it's not something that attract a FLOSS community, self hosters etc who are the sole possible initial mass.

For them a relay offering a Reddit like UI, a Discord like UI, a direct messaging UI (like emails) with media support (blossom) is something juicy.

Offering a Twitter like experience, with a to 3 small community is not juicy

Nostr needs groups to be a Usenet/Reddit clone, a Discord clone, a Matrix clone (meaning conferencing) to be a unique communication tool for anything.

The idea of following people not topics, at maximum filtering with tags is theoretically sound, but practically useless because such setup is something extremely few understand and curate enough, so can't be successful

End users have discovered the power of integration, they want everything apps, a leap towards the original computing model, the OS add as a single, easy to mold environment, where anything is integrated and accessible. Emacs is the best living vestige and example.

Single purpose apps, not integrated with anything are commercially interesting, but not what users want but what tech needs mandate. Having copy/paste and drag&drop as sole IPCs is not tolerable anymore.

Honestly the best moderation is personal, so part of a client, who select tags, npubs, Bayesian filters, * at subtle user will, not someone else. Sure anyone should be king on a personal relay but this decentralisation model is hard to be usable: you can get only messages from certain relays, not certain users, making hard to follow anyone if relay moderation kick in and only few always run their own relay.

User moderation is like classic Usenet Killfile, information flow freely, anyone get only what he/she want

Me personally a built-in client, to serve proxy-ed by NGINX directly.

Nostr actually do much, but lack a single package who do anything, chat for friend, chat for community, short form public notes, long form tagged to create something like Reddit, or the ancient Usenet combining tags to filter out "the feed" and with Coturn VoIP.

We are heading towards the anything apps but apparently so far it's a thing interesting for too fews to came into life

multisig is the way...

It's better a secondary pin to show just certain informations, something who is partially true and anyway plausible. No one can tell if you hide something aside.

AFAIK for smartphones no one have coded it so far, we have something for GNU/Linux desktops over Fuse.

I've talked in theory, because it's perfectly possible but apparently no one have implemented that so far

Actually the better duress pin is fully deniable encryption: you set certain policies on data, you insert a pin and only the data tied to that pin are visible. Those who see can't tell if there is something else hidden. This way you're compliant and yet still private.

Radicle is the most reasonable choice, actually all FLOSS projects should be on Radicle (or any equivalently P2P system). Unfortunately most Devs fails to understand themselves the value of private property for digital things. They understand for a car or a home, but not for digital stuff.

Similarly most do not really care about free socials, not understanding the effect of censorship on public thinking.

You need iron for LoRa, so far I know no LoRa handheld device

question: would you go to a tense protest with a spyware device in your pocket?
