Show HN: I've built a bot that pins links to the bottom of Slack channels

I'm launching this bot today. It allows you to easily configure self-service links on a channel-by-channel basis, saving time and avoiding unnecessary chat. Bookmarks for Slack.

The bot works by monitoring Slack and periodically reposting pinned links if there have been messages in the meantime - ensuring that important information is always accessible. Old messages are cleaned up to maintain a pristine channel history.
