My one quibble with the article is that calling Reading a suburb of London is quite misleading. I understand (North?) Americans use the word differently to Europeans on the whole, but Reading is a Medieval town with a net commuter flow inwards - it's the local hub of economic activity, and is the largest town (it hasn't got city status) in the UK.
For context, in terms of its economy, size, distance from London etc, it's not much different to calling Oxford <edit>or Windsor</edit> a suburb of London.
