Very interesting. I have my @Alby wallet address set up in my various clients. On Primal I am now receiving zaps in that Alby wallet but can only send zaps with sats I have in my Primal wallet (i.e., purchased as a bundle through an IAP). This is a fascinating protocol across the board. I can definitely see the potential of the decentralization of social. It feels  while like the early days of the World Wide Web. 

 Indeed!

Please remember that the wallet to receive zaps and send zaps does not have to be the same one, it's a separate flow 😉
