Bragster, a social network based around 'challenges' and betting (think Double Dog Dare meets Jackass online) has launched an online series helmed by former Kate Modern producer Pete Gibbons. Centred around - you guessed it - challenges, the show Neg Versus sees a Channel 4 presenter taking on dares set by the community, and sounds like it could be fun.

Michael Grade (in his capacity as executive chairman of ITV) has called for better signposting for online TV. According to Broadcast viewers don't understand what they're getting themselves in for online, as they do with the clear watershed on linear TV.

I'm pleased to see him talking about content identification - and a viewer's trust in the broadcasters to make these calls - as part of the content provider's value. We too often set up false competitions between broadcasters trying to be cutting edge, and the boring editorial policy department telling them they can't be. Far from it, the reason to have editorial policy is so that we can identify boundaries, and when we need to alert viewers to difficult content, precisely so that brave decisions can be made, and content that is too shocking for children can be produced in the knowledge that adults will be able to choose to watch it.

Virgin1 has launched a new online-only drama, entering the surreal world of David Raymond Hugh aka Dr Hoo. The low-cost show, brainchild of actor Stephen Lord, capitalises on Virgin1's reputation for cult and sci-fi programming, and is off-beat, and relatively impenetrable. Clearly intended more to ask questions that provide solid narrative, it hopes to hook viewers with a simple conundrum: what the hell is going on, and what does it have to do with Mauritius?

Starring Ian Hart, seen more recently in Harry Potter, the three-minute-give-or-take episodes each follow different formats, so it isn't entirely clear in what direction the show will go. No solid information is given about how it will progress, whether there will be more episodes, etc., and whether it's part of something bigger.

Hints at a long term business model come in the form of the downloadable music video accompanying the show. File firmly in 'watch this space'.
