I strongly disagree with the idea that it’s somehow “unproductive” to work on your blog for a week and publish only one blog post after.
I’m not a blogger. I’m a developer. I wanted to build a blog, and I have one. That’s all. Do I need to write something more? No. It might be “good for my career”, but I didn’t promise anybody to write blog posts.
And you know what’s also totally okay? Overengineering a personal website.
