As mentioned in a previous submission 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.

In the two major versions released since then, I’ve made several improvements:

* added support for Lobste.rs

* switched from scraping Hackernews' HTML pages to using the official API, as suggested by another HN user

* replaced the JSON file-based storage with SQLite

Let me know what you think, and whether this would be useful for you.
