I love it too but this only becomes worthwhile if you manage to promote this post in social media somewhere. If you don't already have a strong social media presence or don't personally know anyone who does you can forget about it.
And here on HN you really have to get lucky, post at the right time and hope the flagging gangs don't get you.
I could not disagree more. This sort of thing is a public service. Even if only a dozen people find it valuable, it can be exceedingly valuable to them. It's worth putting this sort of thing on your website for that reason alone.
In complete agreement, I will add an anecdote from my experience:
I have a tiny hardly updated blog where I post stuff I do and assume nobody at all will ever read it. A month ago I got an email from somebody asking about a detail because her granddaughter's toy has the same problem that my daughter's did. It is so rewarding that some work I did for myself can continue to have value for people across the world.
