BBC News:

The Internet Governance Forum has only just started but already there is controversy surrounding freedom of speech online.
There are several reports on the blogosphere that the Greek authorities arrested a man last week for linking to blog posts hosted in America that satirise a Greek businessman.
Antonis Tsipropoulos was arrested, say reports, for linking to a website which satires Dimostenis Liakopoulos, a Greek tele-evangelist.
Mr Tsipropoulos is the administrator for a Greek blog search engine, called blogme.gr.
Bloggers are describing this as a "spectacular own goal" by the Greek authorities, especially given the fact the country's prime minister Konstantinos Karamanlis and minister of transport and communication, Michalis Liapis, are attending the IGF's opening ceremony.
