I have just looked at mine and even though the recommended for you page is alright the rest of the tags up there aren't. For instance I have a tag on mine for biomedical research! WTF! I have never ever in my life looked at videos on whetever biomedical research is.
It seems to me all sites are as bad as each other as on here on my recommended for you I get shown pics of naked men! Now why the hell would a hetrosexual man who's favourites are full of women be getting recommendations for naked men! DA's need to be fixed just as badly as youtubes.
that site is horrible for picking up on tags, cache, etc from other sites. I am not cursed with the stupid algorithm of YouTube, but I'm not on there long enough to fall prey. I've found out that logged out actually triggers less of their stupidity, don't understand that concept but that's google for you.
