The Chronicles of Narnia: in which order to read them?

Apparently, many fans of Narnia are divided over the order in which the books making up the series should "properly" be read, with staunch proponents of reading the books in the order they are published (which is almost, but not quite, the order in which they were written) and of reading the books in Narnian chronological order (i.e. in the order in which the events described by the books take place).

Two arguments for the "proper order" are here (strongly in favour of publication order) and here (tries to present both sides, though I'd say with a slight "publicationist" bias). Both pages also give the books in both publication and chronological order.

What's your take on the issue?
