The typical problem of a centralized infrastructure.
Indeed:
> This means each user gets their own Timeline partition, randomly distributed among shards of our horizontally scalable database (ScyllaDB), replicated across multiple shards for high availability
Thank you for the feedback, I know there are still several rough spots to be fixed.
Nostr is a protocol that has a lot of potential, but there are tradeoffs, it now has a large ecosystem and requires learning some new paradigms, and being completely decentralized the terminology is also becoming more standardized and consolidated over time.
This onboarding system is meant to try to explain them, certainly not for people who want to quickly enter an email and a password and start using a specific app. For that one can precisely download an app and use the built-in onboarding, often apps create a profile without asking for anything and invite afterwards to save the credentials.
These are different paths for different needs, the good thing is that with Nostr you have a choice, and when you have created your digital identity, you can use it anywhere.
Statics blogs are cool but you have to manage them uploading the content every time. The interesting aspect of this solution is that you can use whatever client that supports long format (https://habla.news, https://yakihonne.com, https://highlighter.com, etc) to write your post, and your personal blog is automatically updated. No fuss.
You should take it upon yourself to save your data, if it is really important to you, so that if all your relays fail, you can simply rebroadcast all your events to a new one and you will be fine.
It's a problem solved in a collaborative and decentralized way.
I used Svelte for convenience, so you need npm (or equivalent), but only if you want to develop/extend the project.
If you just want to use it, the html template is sufficient.
You can use any qrcode reader and simply concatenate the data streams. As usual if the specs are open source you are always able to recover the data, even without the original tools.
May I ask you to elaborate on this point?
