Earlier quoted context omitted.
Using a term like 'hn' isn't really a representative example, since it's unlikely that any advertising would be purchased for such a term or have any custom "knowledge panels". So, first, turn off AdBlock (if you hadn't already done so), then try a more representative query like "flowers": http://i.imgur.com/jsx1feJ.png It's a big difference, and these different experiences with Google could just be a matter of which…
What result do you expect for something as vague as "flowers"? Try something like "flower delivery " or "hydrangea" to see a useful search result page.
(Note that while DDG's results page for 'flowers' is cleaner, the actual results are similarly shit.)
