Here is the material I mentioned at the April 22 meeting.
The first doc is data from the first SocialData survey in 2007. Werner Brog presented the results of the 2009 follow up survey at the City Council on April 26 tho I haven't found an electronic copy yet. It was reported in the Herald the following day.
The second doc is the Powerpoint I used for the Transportation talk at the Great Unleashing on April 10.
