Bobbie Johnson stands in once again for Aleks Krotoski while she takes a well deserved break after handing in her PhD thesis as the long struggle to become Dr Krotoski comes to an end.
So this week in hot seat, Bobbie catches up with some of the interesting people in the heartland of the hi-tech industry: including one man who is attempting to turn the entire web into your playground, and another who wants to take online maps to the next level.
On top of that we hear the latest news - including details of Wikipedia's three millionth entry and the first mobile phone with Welsh predictive text, and weget back into the lift with James Proud of giglocator.com for another Elevator Pitch.
