This is just a repeat of http://news.ycombinator.com/item?id=430577 only now it's the BBC writing about it, rather than the original page.

I wonder if someone at the BBC monitors HN - it's not the first time a link has appeared here, only to be followed promptly by an article on the BBC web site.

Nah, probably not.

Even Jeff Atwood has a take on it http://www.codinghorror.com/blog/archives/001210.html (I posted that version because I suspect that it is all too easy to ignore such common issues in the race to get some code operational plus he gives some explanation of the key issues.)
