After the launch spike it was steadily going down for 8 days, but then jumped to a steady ~900 accounts per day - strangely uniform.24 Oct 2026 14:51 +0000at://did:plc:3guzzweuqraryl3rdkimjamk/app.bsky.feed.post/3mymwx4sf3k2ohttps://blacksky.community/profile/spacecowboy17.bsky.social/post/3mydzsfpj4c2iThe last few weeks show a steady growth of likes, while the number of posts and likers has remained relatively stable. Potentially the Discover feed algorithm getting better. I've seen some positive sentiment towards Discover in "Discover feed" search results.21 Oct 2026 01:48 +0000at://did:plc:3guzzweuqraryl3rdkimjamk/app.bsky.feed.post/3mydzsfpj4c2ihttps://blacksky.community/profile/spacecowboy17.bsky.social/post/3mybykgsvws26My internet was down.

Imagine all your episode plays get recorded similar to teal.fm for songs The biggest issue with podcasting is that it is not an inherently shareable medium. Automatic play tracking and collaborative discovery can change that.

But almost always it preloads the N+1 page right after it fetches page N. That is, the request for page #2 comes within a second of page #1.04 Oct 2026 21:09 +0000at://did:plc:3guzzweuqraryl3rdkimjamk/app.bsky.feed.post/3mx3cqng3bs2dhttps://blacksky.community/profile/spacecowboy17.bsky.social/post/3mwhdksf4bk24If you want to get foryou.club/stats programmatically and show it to users of you app then you can use this endpoint: https://foryou.club/xrpc/club.foryou.getStats26 Sep 2026 22:30 +0000at://did:plc:3guzzweuqraryl3rdkimjamk/app.bsky.feed.post/3mwhdksf4bk24https://blacksky.community/profile/spacecowboy17.bsky.social/post/3mwcnanbzh225 [contains quote post or other embedded content]25 Sep 2026 01:40 +0000at://did:plc:3guzzweuqraryl3rdkimjamk/app.bsky.feed.post/3mwcnanbzh225https://blacksky.community/profile/spacecowboy17.bsky.social/post/3mvfv4bu4bk2rLast week I ran an A/B test in For You where the treatment arm had a higher penalty for popular items and items with more paths leading to them were boosted more.

To do that I just need to make For You only pay attention to the posts authored by users and liked by users with even hash values of the DID.

In fact it has many algorithms - custom feeds. You can choose which one to use. What does it look like?
