Recently, I've been using HN RSS (<a href="https://hnrss.github.io/" rel="nofollow">https://hnrss.github.io/</a>) to get alerts when specific keywords get mentioned on HN. Really useful tool! The underlying data comes from Algolia's HN search engine (<a href="https://hn.algolia.com" rel="nofollow">https://hn.algolia.com</a>), which is neat to run some searches and understand which keywords can be interesting to follow.<p>Thinking about following Subreddits with filters on keywords through RSS, instead of regularly checking into Reddit, to save time and cut through the noise.
