The Pop!Tech 2008 conference is underway and it sounds great. Summaries of many presentations are on their blog and you can also watch video. A shame (for me) that it’s in America but fantastic that anyone can watch it all for free.
UPDATE: It looks like all the video I linked to is from past conferences, with the most recent that shows up in iTunes being from 2007, published in June 2008. You can however watch the event live today and tomorrow (24/25th October) between 9am and 6.30pm in an unspecified timezone…
