Welcome and congrats - what you figured out in just few days is the most important aspect of #nostr ..  you own your data and you can view it through 100s of clients  .. for example , I am writing this reply from my own website without having to use any client  !  For creatives , this is a boon - because now you are not locked into one platform .. and your followers can reach you from a client that suits their needs .. and of course they can zap you from anywhere !
