It's Nstart, not Njump :)

1) I don't know how to make more clear right now, it is written, two times: "We offer you the possibility to copy the full following list of some Nostr users, so you can start your Nostr journey with a feed full of posts from already curated individuals." + "See the same things these Nostr users are seeing in their feed".

I understand that with this kind of UI the user expects to follow users, not their contacts, but even if you misread it's not a big issue having 500 followers, you can remove them as soon you find them not interesting.

2) Optimistically speaking every non-web client should support *only* ncryptsec. However Nstart will have a companion app to manage this stuff.

3) I don't have stats yet, I'm planning to collect some data anonymously.

4) Please open an issue with the iphone model / IOS version and possibly the qrcode.

5) I don't know any resource about that, it's definitively needed.

6) It's in development, see point 2.
