Note

Some websites do not work well with Reader Mode. If the submission URL points to a domain with known Reader Mode incompatibility, the link cannot be opened in Reader Mode.

Syntax highlighting

Quotes

Quotes are indented, italicized and dimmed in order to distinguish them from the rest of the comment.

Hacker News and forum idiosyncrasies

`Code snippets`, @username mentions, $variables and URLs are highlighted.

References

References on Hacker News are formatted as numbers inside brackets. circumflex highlights these numbers for easier cross-referencing.

Categories

Headlines containing the text Ask HN, Tell HN, Show HN and Launch HN are highlighted.

YC-funded startups

Twice a year, Y Combinator funds start-ups through its accelerator program. circumflex highlights these startups to signalize their affiliation with YC.
