I missed this when it first ran, but back in March The Times listed fifty-nine things we would never have been told if it wasn't for the Freedom Of Information Act.
There are no great scandals here, of course, or state secrets, but it's interesting to see the sort of things our masters are unwilling to tell us. Also interesting is the revelation that the Thatcher government was planning an operation to find the Loch Ness Monster using trained dolphins. Bless.
