I noticed that when youtube implemented the auto-play feature on the homepage, whereby you hover the mouse over a vid, it expands slightly and starts to autoplay the vids, that it actually puts the vids in to your watch history, even if you only watched a few (2-3) seconds. After this i noticed that my recommendations got crappier almost instantly. Basically, I would see something with a 'nice' tumbnail and hover it. Since then, everytime I open youtube, i need to go into the preferences and disable that shit, so not to pollute my history, and thus pollute my recommendations. I clear cookies when browser closes and this setting doesnt get saved, for some reason, google isnt smart enough to save these settings / preferences to my account like all the other setting, oh no, its controlled by a cookie. This may have already been scailed back abit since I first noticed it, so maybe not 100% accuarate anymore, still pisses me off.
