Regarding the zapping and failing on some recipients it may have to do with backend provider for lightning. Right now I'm using Wallet of Satoshi for receiving as they were more stable than stacker news and strike, but this seems to be a moving target.

I missed the nostr nest as I had a weekly game session last night. I would like to see reactions expanded upon. The NIP25 for that kind allows for more reaction types and this isn't used anywhere that I've seen.

And Id like to see the option for downvotes. While many like living in participation trophy bubbles where the world affirms all is good, having some cheap indication of dissent without requiring a respondent to write it out as a reply has value as well. Replies and threads work best for discussion in kind 1. Using a reply note for simple "I like this" and "I don't agree" is just a more costly method of kind 7 (nip25) and a misallocation of resources for all stakeholders involved
