From the Guardian.co.uk (Where’s the American media on this?):
Facebook, the world's most successful social networking site, has officially launched in Arabic, tapping into a potentially huge market in the Middle East and beyond, the company has announced. …
In Saudi Arabia the site has more than 250,000 users and in Lebanon more than 300,000.
Arabic, spoken by 250 million people – and Hebrew, spoken by 7 million – will now be available from a drop-down menu at the bottom of the homepage. …
Fifty million of the world's 250 million Arabic speakers already use the internet, but Arabic only makes up 5% of global web content.
