Kuba's Journal - Launching Lycan - a search tool for your likes
You know that feeling when you’re trying to find a post (skeet) that you’ve seen some time ago, and you can’t find it? It happens to me all the time. Let’s say someone from the Bluesky dev team wrote some piece of technical detail, or some ATProto developer from the community posted about their project - I know more or less what I’m looking for, but not enough to find it in the global search. But I know I probably gave it a like, because I like everything 😅

Here's how we leverage @semble.so's wonderful service in search results 👀. This is currently the only working search integration but 20+ more are in the works right now!
I was bored last night so I built a tool for searching @leaflet.pub articles: leaflet-search.catabush.com. Currently built on a cache of over 800 articles from active publications, and will be updating daily to bring in new articles (as soon as I finish that part).
For me personally there is a journey here - I was a firm believer in archive everything. This peaked in a period where I was very interested in IPFS, CIDs, CAS, etc. Now, the next step. Post-Archive(-Everything). Through a series of conversations I came to the conclusion that forgetting is probably more powerful than remembering. The links in this collections play a similar note, or are related to my understanding of this.
my hot take is that @semble.so is on par with traditional search engines for atproto related topics (and it's only curated by people!)
