I've built a daemon to automate monitoring topics on Hackernews. It takes a list of queries (say, "Ruby", "C#" or "Laravel" for example) and exposes stories that match them through an RSS feed.

I've made this for my own purposes really but given that it's worked well for about a year I thought I'd share it here for anyone who might be interested.
