kumo
Kumo (クモ) is a Hacker News client with only links.
mechanics
It fetches stories via the Hacker News API. Data is cached to avoid redundant downloads on page reloads. It shows 20 links by default, which can be set up to 500 with a URL hash.
Filters can be set to exclude stories with certain keywords or ones from unsavoury sources. These are saved locally.
