I was like that, assuming people will just throw barrages of virtual tomatoes to my blog posts, then I read a quote from a famous writer: "Your first draft will always be bad. Just revise" (or something similar).

Then I started to write my drafts when inspiration hits without thinking and stopped the moment inspiration ran dry. Then revising/extending as I feel like it. I publish the post the moment it feels complete. The result is https://blog.bayindirh.io.

The gist is, I write about what I want, for myself. It's out there and available. I also submit to here and send to a couple of friends. If I get feedback, that's nice. Otherwise, eh.

Give it a try. There's no need to be blocking yourself out of something you might enjoy.
