The big thing to understand is a lot of people in The Blogosphere(TM) who post articles about UX don't really give a rip about anything other than the pageviews whether it's for ad revenue, establishing themselves as a thought leader, or trying to market their company. Even worse, there are some people who don't even ACTUALLY know much about UX, they just want to post an article about it to spread around LinkedIn and seem relevant by harping about the importance of UX, etc.
Having said all that, if you sift through all the garbage there are some great resources. Some of the big players in the space tend to do it well. InVision's blog, for example. UXPin are pretty good. There are lots of little ones like UXPowerTools' content marketing emails that are starting to do a good job as well.
At this point as someone who is always trying to improve as a UX designer, I have become accustomed to vetting the 100:1 ratio of garbage articles to bad ones.
