With all the controversy around Jay-Z's appearance at Glastonbury this year, I listened briefly to the news this morning to find out how he went down.

The results - at least through the traditional channels - were disappointing. BBC sat on the fence all morning describing a 'mixed response' backed up by a few random vox pops from last night.

So I tried Summize.com, a neat way of searching Twitter. And a good example of how you can survey an audience and get a spontaneous response in near real time.

In just five minutes the picture was clear. Across the entire performance comments were 70:30 in favour. Although this was closer to 50:50 at the start before the naysayers switched off or went back to the campsite to play with their glo-sticks.

This morning most of the views have been on i-Player. Generally comments are positive, with lots of focus on the homage to a certain Beatles tribute band at the very beginning of the set. And plenty of disappointment that the much-rumoured duet with Mrs Z failed to transpire.

P.S. Credit to the beeb. After all they started the whole Jaygate storm with Colin Paterson's infamous interview with Noel Gallagher. Didn't really kick start ticket sales though, did it?
