Problem with using zaps is that they are unverifiable, except for the sender and receiver. Reactions, reposts, comments from with WoT could be another way. I do like the idea of catching up after some time away. It's too bad zaps are unverified, otherwise it could be useful for outside a WoT system and useful for discovery. An invite system into Nostr may help bootstrap a WoT for those that are new, the invite could include a suggested follow list and notes to view and possibly interact. 

 ah, good point

Just wondering out loud… if something like a verifiable zap could be done, would it be a good idea? I can see pros/cons. But seems like a lot of pros around WoT as you mentioned as well as identity-establishment/information quality.

I understand zaps are private, but just spitballing… seems like if sender/receiver/clients wanted to make it reported/verifiable somehow that might be possible? solutions might touch DLCs, inscriptions or an entirely new technology
