How important are reddit-style flairs for people? There’s the raised issue https://github.com/LemmyNet/lemmy/issues/317 which has it listed as a far-future, with questions as far as how to handle federation.
Personally, having at least an initial implementation done on a community level would be largely sufficient, with expansion to instance-wide being optional. The situation I’ve found most useful, personally, is sports-related groups with your favored team being your flair. This gives context to comments without constantly having to say “as a X fan”
IIRC, there’s like two primary contributers to lemmy, and one to kbin. I can understand why features like these are far away in the timeline. But with the influx of people, more contributors can quickly lead to accelerated development, especially on non-core features.
So, fingers crossed.
