Uptime Institute has posted more videos a month after their Symposium event. http://www.youtube.com/user/uptimeinstitute
After only one day there is single digit traffic on the most recent posts.
Videos that have been out for 5 days have 10 - 20 views.
One video that got up sooner and has more traffic is Matt Stansberry interviewing Gary Cook with 186 views, 187 now that I watched it.
If you are going to post content most of time speed beats quality.
