I created a web app that lets you look back on your year on Misskey, similar to "Spotify Wrapped" or "Discord Checkpoint."
When I announced the site on Misskey.io, it received an incredible response with 1,248 reactions and 879 renotes, and so many people actually used it.
While many people have tried it out, some server administrators have pointed out that it places a burden on the Misskey server side.
If I were to create a 2026 version, I feel that ingenuity will be necessary to reduce server load. Also, since the generation of Wrapped was unstable on smartphones and took a long time for highly active accounts, I feel it would be better to fetch data on the server side rather than the client side. (This would make it possible to limit requests to n per second as a service, rather than per device.)
Additionally, while this site focused on statistics such as the number of notes, number of reactions, and top reactions, it might have been better to have a structure that focuses on "reflection," such as looking back at the actual content of the notes.
YouTube Wrapped, which was one of the pieces of content I actually referenced, used an LLM to analyze preferences and trends over specific periods, structured to help users look back on their year.
This became the most widely used service I have ever created, so I was truly happy to receive such a response and feel that I learned a great deal from the experience.
