Most of my personal websites shout into the void. Their content is so niche (poems, conlangs, web coding experiments, etc) that I would be genuinely surprised if any of them suddenly got popular.

I keep on doing my personal sites because I love creating stuff, and I love coding up quirky sites to display my mad work to those rare whoevers out there who share my niche interests and/or stumble across them by accident.

Building quirky websites is also a good way for me to relax because the sort of sites I get to work on professionally - almost always driven by this or that CMS or framework ... they don't inspire me anymore: samey samey samey stuff with just a tiny odd fun effect here'n'there.
