The basic premise is correct. Most people on HN are liable to read too much, and not do enough.
Personally I believe you have to do both for the fastest learning process. The "read, do, reflect" cycle. If you're not actively "doing" then you will read and associate things quite differently. Without doing, you can build up a very strong theoretical knowledge about a subject, but in doing, not realise the correct time to act on that knowledge. It can also lead to analysis paralysis, as you /know/ there is a bigger picture, and you're trying to figure it out - where as the guy who never read, but just learned by doing, never got slowed down by wondering about that bigger picture.
I know people who just do, and never read - they miss out on a lot of shortcuts they could easily learn, or understanding the bigger picture, motivations etc.
Reflection happens quite naturally for most of us here, but you'll often find it works best when you are actively writing ideas down, or communicating them to others. It then fuels going and reading or doing to fill knowledge gaps.
If you're not doing, then the next best thing you can do is mental rehearsal - if you /did/ have to apply this skill/knowledge to a real situation, how would you do it. You can then find yourself self-coaching when you do the activity for real.
As an aside, this is why hobbies are a Good Thing (tm). They allow you to have different sets of associations, so when I'm learning about a new area, I can link an idea to say organising a scuba dive, rather than something like a sprint planning session.
