My favourites were the practically oriented talks, particularly Hugh Morrison of Arrow International project managers, who delivered a well documented and achievable timetable to get the rebuilding under way. Soon after came James Lunday of Common Ground; he's a Scotsman with a genuine plan for urban design based on neighbourhoods and a people-friendly central core - both things I have been thinking, but he said them 100 times better than I could. (It's his field, of course.) Paul Downton also put a high premium on neighbourhoods.
The over all emphasis was on bottom-up people-centred planning. It's over to CERA now, I guess.
There's an excellent summary and comments at Nathanael Boehm's blog, Pure Caffeine. I'll post a link to the videos when they become available.
