Yes, you need a good guide, good general principles so that you're not practicing in the wrong direction. And yes, you need occasional "recitals" where you test audience reactions. But 99% of the work involved in developing any skill is just raw, rote repetition that most audiences are not only not interested in, but actively avoid.
Fair enough. I can see why my comment came across as if I said there were no other options.
But my point is to use resources at your disposal. One of the amazing resource at our disposal today is the ability to cost-effectively publish a half-baked idea on our website knowing that a) that could still be useful for a small section of people and b) its mistakes could be corrected by another small section of people who know the topic in greater detail and c) all this happens in such a way that everyone is, quite literally, "on the same page".
And thankfully, technical blog articles don't attract too many comments on average. Quite often I find that a blog article on a technical point actually advances discussion on that idea.
All I would say is to make a honest effort. Try and do a basic rewrite before hitting publish.
