tl;dr: Surprised by the paucity of real-time geotagged photos on flickr. People seem to upload in batches many hours after the fact. Still looking for a cool real-time geotagged picture feed so I can do some Blinkenlights info visualizations in a web browser near you!

Since 2007, I have over 50000 21000 (29000 non geotagged) geotagged photos uploaded on flickr from cameras most in real-time or near real time (a few minutes to a few hours after they were taken). I expected in 2010 that there would be many real-time geo tagged obsessive :-) photo uploaders like me. Enough to power a cool Blinkenlights info visualization.
- people are concerned about loss of privacy
- uploading with GPS coordinates is too hard
- GPSes are unreliable but getting more reliable every day
- most people upload to social media ghettos like Facebook and Twitpic where most of their metadata including latitude and longitude is lost and/or not available via API instead of "full photos as social object with full-meta-data-preservation-and-APIs-to-get-the-meta-data" services like flickr
