Last year Bill Tancer Analyst and researcher at Hit-wise published results of his study on online surfing data on top web2.0 sites.
Results revealed data on sharing and participation in You Tube, the top video sharing site owned by Google, and posting participaton in relative terms was small. Only 0,16 % of visitors are posting videos and the rest are coming to look , vote and make comments. A similar situation occurred with Flickr, the top photo sharing site owned by Yahoo, its participation in photo sharing was even smaller, only 0,02% visitors posted photos and the remaining 99,98% were surfing visitors. It seems that the idea of voyeurism and TV passive watching has been transferred to the site in part. Creative participation is not that big, but importantly viewing what has been posted interests inspires and motivates the rest of viewers.
A previous earlier study by McKinsey had surfaced 6% posting for You Tube and 2% for Flickr, but probably today they have grown their visits by millions and those results were at earlier stages with less visitors.
Wikipedia had better results on Tancer’s study , Wikipedia the open crowd edit encyclopedia had 4,6% of visitors editing content.
And where are we at ideas4all.com?. In the past 2 months since launch on July 15th we have 0,7 % of unique visitors posting ideas and 1,9% considering the percent represented by the number of ideas posted vs visits.
A good start.
