I like your post. Does this depend on the architecture of nostr? If "Like" info is available in public freely, I feel not right. I rather keep the "Like" data from outsiders who do not read the corresponding posts. Is it better that only users who read the posts have access to Like data so that "Like" bookmarks are only available to yourself?
