Njump target is *not* specifically people who do not know about Nostr. The main goal is to create a link between the web and Nostr, with several outcomes (e.g. be client neutral, permit a fast sharing without JS and relay glitches, improve indexing of content on current search engines, etc.).
Of course, this means it will be used potentially by people that don't know anything about Nostr, and I agree that some elements can be initially confusing. Here are my thoughts about the "gibberish":

Finally, we are cooking up an update that will precisely address the newcomers, specifically the "what is nostr".

Thanks for sharing!
