I thought I’d clarify briefly what h2g2 is about, as I’m a member of it. h2g2 is supposed to be a quirky but factual encylopedia, it is billed as the hitchhiker’s guide to the galaxy - earth edition, and was set up by Douglas adams, who wrote the hitchhiker’s guide to the galaxy.
Anyone can write something for the guide, with the only real standards being to avoid bad language, copyright violations and other things like that, with no actual standards of accuracy.
There is however the edited guide, which does have such standards. Every entry submitted for the edited entry is commented on by loads of other members, who complain if it is innacurate, biased, or have any other complaints. Then, the best of that lot get picked by scouts, (such as me) who are also members of the public who volunteer to search of the submissions, which then get edited. It is the BBC who run the site now, and they have to agree with what we pick, by the way, but I think their priority is avoiding bad language, copyright issues, and things like that.
So the edited guide is a place where the facts relating to the entry should have been checked out, and so should be more reliable as a source of information. This doesn’t mean they have to be about serious subjects, in fact, you can get weird subjects such as this:
http://www.bbc.co.uk/dna/h2g2/alabaster/A724394, as well as more serious subjects. Also, serious subjects can be treated with a sense of humour sometimes.
However, the entry about the autobahm and the national anthem is not edited, so doesn’t have that stamp of approval. It doesn’t mean it is wrong, but does mean it is perhaps less reliable than if it was edited. It is only really as reliable as the source of the information, which seems to be a ADAC member’s magazine.
