I'm suprised by the past tense - AFAIK it's still running and being added to. I check out the new articles on H2G2 quite frequently.
The aim and content are very different from Wikipedia (and presumably from Citizendium). They tend to be quirky, humourous articles on subjects obviously of personal interest to the author (it's a surprisingly good place to look up recipes), often with a British slant. It's good fun, and interesting, but not so useful for actually finding things out as Wikipedia. So it fills a slightly different niche - not so much encylopedia as a good quality pub conversation.
To believe that you're signing the document on screen, you have to trust every element of hardware and software between the screen and the card (at least). All an attacker needs to do is to introduce a suitable trojan/virus on the computer holding the document - probably a PC, probably running windows - and when you try to sign something, replace your doc with one of their choosing. For a system that doesn't demand password entry for each crypto operation - and that can drive users nuts - the attacker can get both the real and other document(s) signed, making it hard to notice.
You can have the most tamperproof card and break-proof algorithm you please, but if you plug it into a standard PC, you are open to all the attacks we hear about every day...
When Concorde comes in over Britain, the air traffic control clears it a huge corridor fare wider and longer than for any other civil jet - and that's when it's actually subsonic. Just like cars on a freeway, as you increase the speed of the jet, you need more space around it to be safe. It may be better over North America or Australia, but you couldn't go supersonic over Europe because of the traffic!
We'll find out in 2002 - there's a joint mission between NASA and the Japanese Institute of Space and Aeronautical Science called Muses-C that is due to try to collect and return samples from an Asteroid.
