I've been thinking about the same thing, but I procrastinated writing up the talk post. Good thing you did it instead. I would like this feature very much.

It's not a widely advertised feature, but the link for people who are interested in random quality (unsifted) video is right here.

I've requested something similar to this before; sort of like stumbleupon, but only in the sifts. That would be awesome.

I've upgraded burdturgler's random feature.

Pqueue spoofs is the new RickRoll.

I've asked Lucky about this in the past and it's a no go. Seems that the bandwidth required to randomize so much stuff would be quite costly.

I guess I asked when the sift was facing some serious financial strain (might still be), but maybe things are better by now.
