Historical canon517

Older ranked records represented before 2025-09-21. Useful for prominence and memory—not total activity.

Recent candidate pool1,000

Newest records from 2025-09-21 to 2026-08-07. The boundary is inferred because original retrieval provenance was not stored.

Analysis availability · Core views

Core views require at least 1,500 total records and 500 canon records; this corpus has 1,517 and 517. Topic comparison is withheld because this corpus has not been topic-enriched.

Historical material available

517 ranked historical records span 14 represented years. Topic evolution is not shown until this corpus has enriched topic assignments.

Recent contenders

What is earning attention now.

The newest-post pool is filtered within age bands, then ranked by score and reply-count percentiles. Posts newer than 7 days are withheld when enough mature candidates exist.

Candidate index is relative to this recent pool, not a prediction of future quality or final Reddit rank.

Candidate-pool signals

Read the recent pool without contaminating the canon.

Every lens below uses only the inferred newest-post cohort from 2025-09-21 onward. They describe patterns inside that selected pool—not subreddit-wide prevalence.

Sampling and methodology

Collected records: 1,517

Represented range: 2012-05-23 → 2026-08-07

The corpus combines a broad newest-post listing with bounded top/year and top/all listings. The interface infers the recent boundary from the newest 1,000 records because original retrieval provenance was not stored.

Older records are analyzed as a ranked historical canon. They can show what was prominent and repeatedly surfaced within ranked retrieval; they cannot estimate total monthly activity, publishing habits, or whole-conversation prevalence.

Recent contender ranking compares posts within age bands using score and reply-count percentiles. Platform attention is not evidence quality, accuracy, representativeness, or future performance.
