I'm much better at writing and understanding code than writing a technical blog. I tried once when I open sourced a new tool, but quite honestly it sucked. It sucked hard. I only ever published one post and nothing else because I just can't write as well as I code. https://samaritan.ai/blog/reversing-docker-images-into-docke...
I think too, you know people from work will see it and you also worry if it may affect the way they view you professionally.
It takes a lot of effort to make it pretty, convey the message and make sure the paragraph flow is there. It's a skill and I think you develop it with time. However, speaking for myself the return on investment just isn't there.
