Google has been disabling natural page scroll of late. Try scrolling SER pages using your keyboard arrow keys and see what i mean.... natural scroll has been replaced by a little pointer jumping from one result to the next, starting at result 1 (which is normally an ad).
Not only they've pushed the organic results down as far as they possibly can (plastering the top fold with ads and google own services), they also make it quite annoying to try and scroll down to them when/if using the keyboard arrow keys (done on laptops alot!)...
It's been around a while. I wonder how much more revenue they get/advertiser loses because of people accidentally hitting enter twice after typing a search. Coupled with the suggestions this actually happens a lot. eg: As you type, a suggestion you want pops up, it is natural to think you hit enter once to select it, then again to do the search and bam you end up on the 1st adwords result page. Bet Google loves those two "user experience" features lol.

In my country,Google Instant had not been fully introduced until shortly ago (not that I had noticed).
After the introduction, I (who was used to pushing Enter twice to see the SERPs, once for selecting the keyword, and once again to see the actual SERPs) found myself surprised many times to land on the #1 page.
I probably contributed (unwillingly) to increase some Adwords bills.
I never saw it only until recently. I'm in Australia. It is spreading now.... apparently.
IMO, this little "innovation" is very bad for online businesses who relay on free organic search traffic. Add to that the recently introduced killer named "instant" and you have the perfect storm for many webmasters from all around the world.
If you are not on 1st result nowadays you're doomed. I can see it across my network of content and e-shopping web sites as well as web sites i manage for my clients. It is getting extremely though to get decent online business while google continue to report exponential growth.
