I think it is beneficial for people needing to buy a non Apple products to be able to use their favorite apps.
This decision will trap people longer in the Apple walled garden.

Interesting. It includes a chip reader too and is really cheap.
I think this would be a reasonable choice for the recovery signer in a 2 of 3 multisig, as long as the chip card is pin protected.

Not currently, since nfc readers for desktop are rare.

How can I use nostr for a community channel for @nprofile…luuf?
A kind of reddit/discord/telegram style chat where users can discuss topics and get help.
Requirement:
- very easy to create a new nsec to get started
- web browser is sufficient
- some moderation tools by an admin (banning npubs,...)
- pinned posts by admin

When I create a new account via the yakihonne website and send a dm to my main account, then I can receive the message with the yakihonne client, but not with Amethyst.
Sending a legacy dm (I guess nip 04) on the yakihonne website then I receive also with Amethyst.

Good article.
In Bitcoin-Safe.org I use nostr for the Label Syncing , Backup , and Multi-party Multisig Collaboration, but I don't advertise it as nostr. It just happens to be a convenient tool for the job.
Zapping is something unique and cool to nostr, but I think it has it's own bootstrapping problem.
It is powerful though for creators, not being at the mercy of a censoring algorithm.

It pulls a summary of the blocks from normal Bitcoin nodes. If an address of the wallet is in the summary, then the wallet pulls the entire block.
This is fast, because only a few blocks need to be pulled.
And it is private, because in each block are 2000+ transations, and it is not easy to determine which one you were interested in.
