It strongly depends if what you write provides value to the readers.

I started blogging 15 years ago and probably what I wrote made some sense because at some point the blog had up to 10K visitors every month and I had many interesting conversations with readers. Also, since then I never looked for a job.

The blog audience also became the initial audience for my 1st commercial software product. The product itself became a stepping stone to another, much more successful software product, but that's another story.

If not the blog, things could've been very much different.
