I think npubs are so quick to make and jump about between (on amethyst) that it's quite nice to have one-theme npubs, a scrapbook npub. It can also be semi private just cos the chances are no one will see it. (If you wanted to have one that is just sorta just for personal use, obviously not with private stuff on it). 

 Yeah!! I can’t jump between npubs on Damus really and I mostly use Damus! 

 Ah, maybe Damus will have that soon tho:) 

 Would be nice !!
