This is becoming really difficult, due to blog spam and SEO. I have so much trouble finding good info that I often end my searches with "site:reddit.com". I hoard RSS feeds collected from sites like HN and Reddit because I know if I lose them I'll never be able to find them again.
How I wish that were the case. Content on a personal website--no matter how excellent--will be invisible and nobody will ever see it -- unless you do heroic SEO or get lucky in an inexplicable way.
Personal anecdote: I created a website on a particular subject that interests me. I've been told by friends and strangers that it is extremely well written and gives a better explanation of the topic than anything else they've seen (at least during the period when I worked on the site). The site has no analytics, no ads, nothing controversial. Just a clean design with text, diagrams, and photos. Google will not find my site using any appropriate keyword. Not even after pages of search results. But Google has indexed it. If I search for "an exact sentence from the site quoted like this", Google finds it.
Self-hosted content in today's web does not survive on merit alone even when it's focused, useful, and free. That's been my experience anyway.
Also, we are not entirely dependent on search engines. A domain expert can link to other articles from her articles, and so on...forming something like....a web. But we need to encourage the practice of linking. So many people write now (typical Medium articles, for example) without linking to anything much, as if they are the only ones to have ever thought or written about their topic.
I would also encourage people to contribute to original project documentation, bug trackers, or mailing lists.
It’s unfortunate that Stack Overflow is the first destination people end up going to. I guess it’s to be expected since many projects only offer static pages and offer minimalist code examples.
The original poster is lucky that they have a blog and their own platform to voice their opinions.
EDIT: anyone can have their own platform, you don’t need to be lucky. It only costs a few bucks to register a domain, and hosting starts at $0.
SO, Wikipedia, and the like not only take and use your work for their own purposes, but are bad for the web. Their effect is to move the web away from a distributed network of knowledge under the control of individuals responsible for their words, and toward homogenized, voiceless near-monopolies of information. They are nearly as unhealthy for the web as Twitter and Facebook.
