When you stumble upon a good article, subscribe to its RSS feed if it has one, and unsubscribe if it gets boring. Eventually you'll end up with an interesting collection of blogs. I wish I could help more, but most of the blogs I follow are probably uninteresting to you.
Yes, I've taken a similar approach with RSS and a subset of social media. If only there was an algorithm which would take a web of links and show a web of related links :)
