Apparently the French have a big thing for justified text.
Now, I've actually studied typography (the study of type!) and know that justified text makes it harder to read. The fact that newspapers use it doesn't mean it's 'better' or 'correct' or.. Grrrr...
Whenever I've shown a French person a piece of text to correct for me (usually a shitty translation I've done myself of something I've first written in English and then tried to translate into French), they take it upon themselves to also justify it left and right! hahaha. When I've received letters from French people they are almost always justified!!
Here is a great example of why justified text sucks!!!!!
