"Your TweepCred / PageRank score caps your reach"
Verdict: GONE from the 2026 open code
TweepCred (the PageRank-style author score with the famous follower/following penalty) exists only in the 2023 repo. The 2026 ranker consumes learned embeddings — 'we eliminated every hand-engineered feature' (phoenix/README.md). No tweepcred, no RealGraph, no follower-ratio feature enters the 2026 scorer.
The code
grep of xai-org/x-algorithm: zero hits for tweepcred/realgraph. phoenix/recsys_model.py RecsysBatch = ID hashes + action history + post age only.
