> How do you know if this article is actually good
By author's name. The problem is, even on sites, where you can subscribe to not the whole site, but particular section, you usually cannot subscribe to particular author.
Then Twitter provides a way to do it. Find the author at Twitter, and subscribe - usually he or she will be announce there every publication he or she made - you can even trivially gate his or her tweets with links to RSS if you wish, using Twitter groups and IFTT.
By the way, if you want to support the author, using Tweeter you can do this too - likes and retweets are valuable and to promote good author among your subscribers is good for everyone.
The problem is authors don't tweet links on their own works only, more often than not they tweet links on many other things, and more often than not, you are not interested in the everything the author read or discuss, but only in his or her journalist works. Technically it's possible to filter this by parsing the pages from author tweet links, and find there his or her name.
