It's a common theme at the Economist to pick out a section of the world and focus on it for an issue.

This week it happens to be the Nordics but in the past it has done China, the USA, France, Singapore, etc.

Once a month or once a quarter I think.

More of than once a quarter, for special reports. But if I should abstain for all technology reporting for a quarter, the "Technology Quarterly" of the Economist is the one I would not like to miss.

The most recent 'Special Report' (this weeks issue) focuses on The Nordics. It's a series of some 5-8 articles in the paper.

The previous special report was on offshoring and outsourcing. http://www.economist.com/printedition/specialreports

It's a series of articles in the same issue, and I guess the submitters are just trying to get the full karma mileage out of it.

One pattern I've noticed lately is that if some topic gets popular people tend to just beat it with a dead horse (reddit works a lot like this). It's a bit like the 24/7 news cycle.

Hence why I believe HN link curation has become popular.

It is the theme of this week's special report. 14 pages on this theme in the middle section, to rip out and save if you would like.
