I have a homapage (just static manual html). I host config examples, for when I'm out and about and I need a reminder. And I write "blog posts" about unique problems I solved. Unique in the senses that a search engine was unable to help me at the time. It is not about reach at all. I write for my self and for the one or two people that are in a similar situation. I know I have helped people, because ~0.7 times a year I get a thank you mail from someone. If I analyse with goaccess all I see is bot noise.

BTW: This video pushed me over the edge to finally start a homepage https://www.youtube.com/watch?v=yDzAAjzbV5g
