Plus: Ten Great Ideas About Chance, buses in Britain, and ages in Brittany.

Ethics of Using Twitter Data

Collecting and publishing data collected from social media sites such as Twitter are everyday practices for the data journalist. But is publishing Twitter content –without seeking some form of informed consent from users beforehand — ethical ?

Carbon Doomsday

Check out this Carbon Doomsday chart which visualizes carbon dioxide levels in real-time using open Air Pollution Index data. The code is open source and was created by a team of eight people, including programmers, designers and marketers from the US, Ireland, Australia and Germany.

More often than not data will show up on your doorstep with a problem… or two or three or more. In the data journalism world, it’s called “dirty data.” Data editor Mary Jo Webster breaks down common dirty data problems you might encounter.

Britain’s Bus Coverage

Brittany’s Average Age

Le Télégramme deciphers the average age of the inhabitants of the 1,250 municipalities of Brittany. (Hint: It’s 41.6 years, but varies widely from the coast to the cities.)
