I did some digging today because I noticed I hadn’t seen any posts from a couple of users I was following on bsky from micro.blog and discovered that their timelines (on micro.blog) end abruptly in late-November even though they’ve continued posting.
Example: Micro.blog - @failbettergames.bsky.social shows a last post of 2024-11-22, but their most recent (non-repost) post was @failbettergames.bsky.social on Bluesky on December 16, 2024.
