A good Fediverse prediction for 2026:

"The new “ #ActivityRank” algorithm in #Loops will prove that ethical recommendations & decentralization can coexist. @dansup’s approach—where each instance trains its own #algorithm while surfacing content across the #ActivityPub network—will be recognized as a breakthrough in solving the fediverse’s #discoverability problem. By the end of 2026, the pattern will be studied or adopted by other ActivityPub platforms."
