I am not saying they were not quality sites or something... I am saying Google fights the technical things SEO's are doing. There are a lot of quality sites without good technical SEO-"tricks".
Also: there seem to be (a lot of) websites which had a penalty in the past and got back into the serps, thus increasing the amount of competition. I do not know if this is temporary or whatever but I strongly start to think this is NOT temporary.
I also noticed a weird error on the results maybe indicating things are still not well enough at Google:
