Bluesky is enjoying a boon in popularity. The API access right now is nicely open, allowing people to create some interesting stuff around it. I like this idea from Matt Kane: a Web Component (<bluesky-comments>) that loads up all the replies to any particular post like a comment thread. Imagine there is a post for every blog post you publish (like we do), instead of writing your own comment system you could just say “leave a reply on Bluesky” and that could be the whole commenting system. I hope get gets proper filtering.

Really like this direction. It feels a lot more interesting than bolting on a traditional comment system, especially when the component stays lightweight and easy to drop into plain HTML.
The only thing that would make me hesitate using it as the main comment layer is filtering. If that part gets solid this feels like a very nice progressive-enhancement style solution for blogs.
