It only sorts by zaps from the op?
Discussion
I think so. I don’t think it moves comments up if they get zapped or anything. Only zaps to OP note.
Don’t quote me on that but that’s how I believe it works.
Watch this
Now my zap sits mid conversation
Ah ok I’m closer to understanding. I wish the release note had been clearer.
Any reply who’s author zaps the original post will be boosted.
If the author has multiple replies, are they all boosted according to the amount zapped?
No it only pins the top zap. The zap has a comment within it. So it displays that zap and the zap’s comment right under the original note.
