I have probably two dozen blogs and initially wrestled with the same thing. If you want to blog, I would be happy to help you find a process that works for you.

I am sure you could find an audience. You sound like a rich source of much-needed wisdom on the subject of small business of a sort that would be highly relevant to lots of people on HN.

Edit: It is also fine to interpret my first remark to mean "No apologies needed re the length. Lots of people here would be happy to read more." I mean, you aren't obligated to start a blog because a random internet stranger flippantly suggested it, but I have the bad habit of taking objections literally when people really mean "I don't actually want to do that" but they don't actually say that, they say "I would, but (reason)" and then I'm all "That's totally solvable!" because I am compulsively helpful.

You can copy and maybe extend your texts from HN and Reddit and post them to your blog.
