Proof of Usefulness Score
Category Standard

XDA Developers is a verified pillar of the tech ecosystem with ~14M monthly visits, significantly outperforming the calibration baseline (HackerNoon's 3M). Although the submission itself was low-effort and lacked data, external verification confirms its massive reach, historical significance in the Android development community, and continued relevance under Valnet ownership. The score reflects its 'Much Larger Scale' status, adjusted for slightly declining market timing and poor response quality.
