I use NewsBlur https://www.newsblur.com to track my RSS feeds, and it's been awesome ever since I moved away from The Old Reader, you have to pay a small yearly fee (currently $24/year), but it has a free alternative (up to 64 feeds)
A great resource to find articles on javascript is http://www.echojs.com/, which is becoming more and more prominent, and is a HackerNews of sorts, but for the JS community.
As far as individual blogs go, I'm a tremendously huge fan of http://www.codinghorror.com/blog/, by Jeff Atwood, a founder @ StackOverflow.
For a full list of the feeds I follow (they're not that many, and they're all tech-related), visit this link:
