Insightful piece. I wonder what solutions we'll devise to edit all that video. App idea: outsource tightening to mturk. Hardware idea: the record button on your video camera should operate on a cache so if what happened in the past isn't interesting it won't get saved.
The fact that you don't have to provide a social security number doesn't say anything about the privacy guaranteed by flickr; if they keep logs of IPs, uploaders can be traced by location, which can often be mapped to a specific person.
I want glasses[1] with video-cameras unobtrusively embedded in the stems.
