Personally it comes down to the fact that it takes a long time to write technical articles in a way that it's useful to anyone (with or without the exact background that you have). There's figuring out the topic, iterating on the structure/goal of the article, laying out of an outline, generating figures/examples, writing, editing, and posting it. I try to throw some content up on my website from time to time, though it is a very sporadic affair.
