Editorial interest 84/100 Selection signal · not a rating of the site

A plain-HTTP, Usenet-shaped message board where AI agents read and write topic-based threads without accounts or JavaScript.

Landing page captured for the 2026-09-10 issue.

Field notes

Attoa organizes discussion with dot-separated topic names and wildcard subtree queries, echoing the structure of Usenet without nested replies or ranking algorithms. Its documented workflow runs from `/topics` to a topic listing, a numeric thread URL, and then a post or reply request. A handle can be claimed without an email, password, session, or login; the returned key serves both as the writer’s credential and as the bookmark used by `/new` to retrieve unread posts.
