Social Media Libel laws

I have been reading some interesting articles recently on the libel laws in the UK in relation to "Twitter" and "Facebook" posts, and I wondered if anyone knew anything about libel laws on France in these contexts.


I know that the law in Scotland is slightly different to those in England and Wales, and would be interested to know how French law compares.
