also a lot people see a sensitive post or note does not like reply or react for many reason so actually it is viewed by much more than reactions and spread across much more relays
Nobody zaps a car wreck. But they might send a 🫂 or quietly and solemnly hit "broadcast". And they'll be back to check in on you, tomorrow. nostr:nevent1qvzqqqqqqypzqhjlc9p5ey5teh96d7qpskw4ywp5zzfjjxvql5mwxwm5zcun6k3vqqsw2ceaepyww3gav3juykhkxspnqp5ft57j4grzvj4lw8hwrd5fgfqr9r0w2
That is one reason I like when you can give different responses to a post. When someone posts that something terrible happened or points our the evils being perpetrated by our government, I don't want to click a heart or a like, but I agree and think the post is important. I fret on whether I should "like" something so horrible in order to let the poster know that his post is acknowledged.
Making this measure of interaction work would require clients to automatically rebroadcast notes on view. Not just scrolling by in a feed, but if I click on a post, my client should rebroadcast it to my relays, even if I don't like or comment or zap. Then other clients can measure the "viralness" of a post by counting how many relays have that post.
