Bluesky Accessibility Observatory

public Bluesky post commits. It begins with archive-format v2 and does not
include the biased April 2026 snapshot corpus.

creation time. description_sample is a deterministic, uniform bottom-k
sample of non-empty descriptions after a 48-hour correction window. It uses

14.5-hour Jetstream file is a short observed window, not a durable census.
Rows contain author handles and DIDs, post URIs and CIDs, post… See the full description on the dataset page: https://huggingface.co/datasets/lukeslp/bluesky-alt-text.bluesky-sentiment
