Same with Sheldon Brown’s website on bicycle maintenance. Much of the information on his site is still the best resource on the internet but instead Google would rather serve irrelevant results that show ads.
Same with all organic content. It's just all bullshit SEO spam now, I haven't landed on some dude's blog in ages, and some dude's blog is my favorite part of the web.
It’s only a matter of time till it gets ripped and hosted on another ad filled website like all the fake stack overflow websites these days. So at least the material is not lost.
Same with images, I used to search for historical images, but it’s all a wave of stockimage this and that, and ofcourse flipping pinterest, which usually is just a link to real content anyway.
Google Search is aptly named, for finding something relevant and without ads plastering is almost impossible.
