Recently YouTube added a feature called “Watch it Again” where it recommends videos you have already watched. It is a little crazy-scary how good its algorithm is because everything to date it has recommended has been awesome stuff that I was in the mood to hear or see but would probably have never thought of seeking out if it wasn’t recommended. Get out of my head Google!

Not for me. I would have to draw from much further back for that. It’s always stuff I’ve watched in the past month or two.

Then again, that seems to be how long YouTube can remember that I’ve watched a video–even though it’s still in my YouTube history. It won’t mark them as watched.

Hah, yeah, that is almost worthless for me. So far it’s only stuff that I watched maybe a week or so ago.
