My view of the social media aspect:

The Head of House (or the person/people with power) will get access to an iPad. This iPad will act as a similar way to the HoH in US BB, where they can make a blog/upload photos from this iPad. It will be extremely restricted in the fact that they won't be able to communicate with people from the outside. I believe that they will be able to read filtered tweet feed on a screen in their private HoH quarters. These will be moderated/filtered by BB staff in the sense that they won't give away other housemates' conversations/nominations, but will give an indication as to the general view of other housemates.

The HoH should also be able to use the iPad and be the only person to control the shopping budget (+ a separate HoH bonus budget to spend on things they want for themselves).

If they did give everybody a device, it would be cool to restrict the devices so that housemates can use them to communicate with each other, and the messaging bubbles appeared on the TV screens as they were sent in the highlights show. However, that's probably overkill and would reduce the show to seeing a bunch of people sitting texting each other!
