So we're blogging live from the floor of Extreme Computing 2002 in the Camden Centre, London. It's packed to capacity, and there's a myriad of bizarre stalls showing off - and selling - everything from tea towels with Google searches printed on the front to amazingly ambitious public database schemes. On stage, George and Freeman Dyson, and Tom Standage, have just blown us away with a discussion that rampaged from biotech to (nuclear powered) space flight, and now the lightning presentations have kicked off... and someone's doing an origami demonstration. Things go downhill shortly when I join Tom and Ben on stage to defend blogging against charges of being "fashionable".
