That's amazing. I've been thinking over the last few weeks about a good solution to bookmark all the valuable stuff I discover. This is going to be the perfect backbone. On top of that, I guess I'm going to use hashtags like #apps #bitchat so I can categorize the bookmarks. All I need to build is a frontend that displays the content based on that, the way I want. I also tried to achieve that with specific zap amounts - let's say I want to bookmark something as an app, then I zap 5 sats; if I want to bookmark an article, then 6 sats, etc. - but it didn't work. Indexing based on that seems too slow, but I only tried to vibe code it ao far 😅
