Same here, but I'm considering adding it. I already have HTML, so it can't be that hard to add another format. More onerous is needing to write a blog post at least once a week.
That's big web thinking. A small website doesn't need to be discoverable. It's supposed to be for you, and if someone else stumbles upon it, and finds it useful or entertaining, that's a bonus.
I suppose just having the website online is enough to make it discoverable by search engines.
I have no idea how but people independently discovered my work and submitted it here on HN, reddit and lobsters. For a long time I avoided submitting it myself because I hate advertising with a passion and I absolutely did not want to advertise.
Really made my day when I came here and saw my domain on the front page.
