Hacker News Reader

It's explained in the "what is this?" link at the bottom:

SELECT * FROM bigquery-public-data.hacker_news.full WHERE text LIKE "%I predict%" on the Hacker News BigQuery dataset, plus some mild preparation.

I think the point is that they want a link to each comment in its original context.

ah, yeah, that seems like an easy feature to add.

If you click the username, it links to the comment on HN.
