A good way is to pay attention to where the linked articles on HN/Reddit are published. A few months ago, I made a habit of searching for an RSS feed whenever I read an article that I liked. Searching is the right word here, usually I have do View Source and search for 'rss' or 'atom'. If there is a link, I'll add it to my reader. Sometimes the feed link is not present on every page of the site.

It will be a slow start, because the more interesting and personal blogs don't update daily. It takes time to write a good article and the good ones also wait until they have something interesting to write an article about. But over a couple of months, I already have over 70 feeds in there and now opening the reader to see what is new is a fun activity.

Pro-tip: it is hidden well, but one can also follow Youtube users and channels with RSS and avoid the spammy front page.

I'm curious what reader you use. I almost never have to do the searching you describe, I just paste the main URL into my reader app (The Old Reader, https://theoldreader.com) and let it find the feed.
