If you're interested in more of their particular quirks of style - or want to see how well-specified the writing style is for a major magazine - most of their guide is available online at http://www.economist.com/research/styleguide/.
I also have found some success in trying to avoid pronouns when writing. It can lead to weird phrasings where one's opinion is stated as a fact but a majority don't seem to care much about that (pedants are in a minority). See!
In blog entries they use initials since a variety of writers write for the blogs and to avoid confusion. Special reports have bylines too. While there may be contributing authors for a report it's byline is by the author responsible. Some guest articles are also signed, for example if Tony Blair writes a piece. The final article with a byline is the farewell piece by an outgoing editor in chief. Alas, this is a rare event, since the newspaper (which actually insists on referring to itself as a newspaper) had 16 editors in chief since it's founding. That was in 1843.
The paper's point is that it's a product of all editors and should speak with the voice of the paper. Thus the "Your correspondent" moniker.
They certainly never shied away from opinion, or tried to cloak uncomfortable opinion in weasel words.
How do other languages handle it?
