So, you say that people are more interested in "web content about Facebook" than "web content about weather", and they aren't typing in "facebook" to get to facebook.com, and going through google (likely unintentionally)?
I actually watched a friend google Facebook and go to the website through the results... It seemed so strange to me. Maybe some people have become trained to do that? I've only seen it once but it stuck with me as odd.
1. Type google.com into the address bar. They don't know that modern browsers can directly redirect search input to your favorite search engine.
2. Type the domain (including extension) to the google search input.
3. Click on the first link.
The most horrifying part is that they probably do this every time they want to visit that domain, and don't even know what a bookmark is.
Never mind about writing <html><head></head><body><ul><li><a>link1</a></li><li><a>link2</a></li>...</ul></body></html> and using a simple list of their favorite links as their home page.
My only consolation is that when these people grow up and have some money to spend, the HN crowd will all look like Odin, with all the magic we can work using our mastery of the runes. I bet I sacrificed some of my eyesight by sitting too closely to old, low-res CRT monitors, too.
