The issue is not that you shared your experience but it is that you provided no real insight or value into how to get a job at a start up. This article is just platitudes referencing your anecdotal experience.
If you're going to post your personal blog, here are some examples of decent posts:

What do they have that your post doesn't? Depth. They bring a topic up and have insightful perspectives on that topic. If your goal is to write compelling or informative articles about getting a job at a start up then you could speak with founders/engineers about what they're looking for in a new hire, etc.
I'm sorry if you take it personally, I'm just giving you honest feedback.
