Here's an example. I remember reading a few months ago about how to do a hexdump on /dev/urandom to create a Matrix-style scroll, and to "look busy in front of your boss". So I did a Google search for "look busy with /dev/urandom" and sure enough the blog post I was looking for is the first result:
http://jeromenicholas.blogspot.com/2011/03/look-busy-when-yo...
Now, I don't know if it's just the first result for me (I'd like to hear what others get), but that post doesn't come up in the first 50 results on DDG, using the same search string. Whether Google's algorithms are better overall or they have been trained better by me after years of searching, the results for obscure searches are simply better 95% of the time.
Of course, there are still the 5% of searches that end in frustration. Example: there's an email product called Prayer. That's all I'm going to tell you. Go ahead, try to find it. The correct result is #1 for me right now, but that may be because I clicked through dozens of results before I found the right one. It wasn't on the front page the first time I searched for it.
