I can’t even fathom how anybody thinks that this is fine on any level (from the mentioned site, the first result about brownies for me, and one of the first few paragraphs). For a while, I rather pay for cooking and recipe books, because wasted time on these texts would worth way more than that money. Especially that even the recipes themselves are terrible most of the time on the internet.
But after a thread a few months ago here on HN, in which people praised w3schools how it’s really a good site, I’m not surprised on anything. If the people who really should know how these things work, and that there are better free alternatives for all content on that site, even encourage this bullshit, then this won’t improve at all.
