Our long-term focus is really on the instant answers, and we hope to really build up the DuckDuckHack platform to a point where the majority of searches have instant answers on par or better than the links.
Of course, basic link quality is still par for the course. We have worked a lot this year on better language support so if you type say in Finnish we recognize that and adjust the results appropriately. For truly localized stuff (like restaurants, transit, for example), we really want to attack that via the instant answers.
In Sweden - the current interest rate is 1%. This is financed by the state and is low because of a multitude of factors. One being that it is practically impossible to default on the loan. It will stick around.
(The tuition is free for higher education in Sweden, but you can choose to take out a loan for your living expenses during your study period).
Parts of some large municipalities and hospitals (City of Gothemburg, for example) are trying it at a much larger scale than these companies, and the results will be much more interesting. It's still not widespread though.

I think it's pretty safe to say that "Sweden" is not moving to a 6 hour work day yet. This is two, incredibly small companies that are doing so.
If it was Ericsson AB or any of the industrial companies (Sandvik, SCA, Volvo, SSAB ie Swedish Steel) however...
This did for some reason wake a bit of nostalgia in me from the earlier days of the public Internet. I bet it's the spartan design and the lack of anything else other than the to-the-point content. (That said, fascinating content - might try it out!)
It's also worth mentioning that the Federal Bureau of Investigations (FBI) also served the non-profit Internet Archive (IA) a National Security Letter (NSL) in 2007.
After a joint lawsuit filing of the Electronic Frontier Foundation (EFF) and American Civil Liberties Union (ACLU) challenging the NSL, the gag order and the constitutionality of the NSL on behalf of the IA - the FBI withdrew the NSL as well as the gag order. 
As such, the gag order and NSL was never invalidated in IA, Brewster Kale (ACLU, EFF) vs. FBI.
Unfortunately, blip.tv is gone. There's no sure indication that all the content will be migrated, but the odds are low - there was a lot of content at blip.tv. Luckily, most of it is archived and being uploaded to archive.org and will be available sometime.
