I'm not signed up to YouTube therefore have no home page to flood with anything therefore no matter what I watch, the next time I'm browsing YouTube nothing in the right pane reflects previous browsing history only other similar examples of what I'm watching at the moment.

I can watch all the political videos I want and as stated when I'm next browsing it becomes a nothing to see here officer kind of thing recommendation wise, plus I get non of the adverts others seem to suffer.

Maybe it only affects those with a YouTube account, certainly doesn't affect me.
