Oh, such a dramatic week. First, Manchester United footballer Ryan Giggs – now known to have had an affair with Welsh model Imogen Thomas – put his foot in it by attempting to sue Twitter after some of its users posted his name despite the fact he had taken out an injunction preventing UK media from naming him. The only problem is that it caused so much outrage that Liberal Democrat MP John Hemming used parliamentary priveleges to name him anyway. D’oh!

And today, Twittersphere is buzzing with tweets about Cheryl Cole’s shock sack from the US X Factor – less than a week after her debut on the show. Were producers unfair to the Geordie lass or do you prefer Nicole Sherzinger anyway? Decisions, decisions…

Here’s what else we’ve been hooked on this week:

Dubai TRA praises social media

According to WAM, the UAE Telecommunications Regulatory Authority (TRA) has begun using social media on its own website and is advocating the use of social media in enterprise communications strategies.

“Social media can be defined as an established and evolving channel that needs to be part of overall communications and capacity-building strategies,” said Mohamed Nasser Al Ghanim, TRA director general. “It is a key component for companies whether they are for profit or non-profit, because it provides them with greater opportunities to share more information about the important work they do, and it helps them in obtaining the required feedback.”
