You definitely should go for it. Writing helps a lot in organizing your knowledge. I have a technical blog where I publish my small discoveries or results of some longer research. Each time I write a post some interesting questions will pop up in my head (even when I feel I know the matter very well). Additionally, I am really happy when I can give someone a link to my post that answers his/her question. So good luck and I hope we will see your blog post one day on HN :)
