HN is the only site I visit for tech news. The rest of the news I get through newsletters. I follow about 20ish, which I sift through each week to stay updated.
JavaScript Weekly, HTML5 Weekly, Node Weekly etc has me covered and a lot less stressed about staying updated. Basically, just Google [Topic] weekly or newsletter and subscribe to a few. If they don't deliver, just unsubscribe.
Firstly, you can't possibly learn everything. I once was in a spot where I tried everything, desperately trying to learn. This was probably the worst part in my learning curve - not being able to tell what's important and what's not.
So, I'd recommend you to pick something and stick with it for a while. This way, you give yourself time to do some focused learning and keep up with specific best practices. Last year I focused on Angular and Node. This year it's React and RxJS.
Tldr: choose an area, focus on it for a while until it sticks. Put the other techs aside until you've learned.
