This is my 5 minute Ignite Where presentation at Where 2.0 2009, on Future Location and Social Networking (what we're doing at Spatial Networking with our whereyougonnabe). The Ignite format consists of 20 slides which auto-advance after 15 seconds.

This is an extract from the O'Reilly video of the Ignite session at where.blip.tv/file/2141261/ (under Creative Commons license) - this clip starts at around 35 minutes in.
