The New York Times ran a piece on the social networking site StumbleUpon yesterday. StumbleUpon has 3.5 million registered users. They start with the idea that StumbleUpon gives people recommended web sites based on their interests (sites they give a “thumbs up” to) and history of previously stumbled sites. They want to help you discover new sites that you will probably like.
According to Quantcast and the data I ran Alexa, traffic from StumbleUpon still lags behind Digg. However, in my experience it’s easier and quicker unless you get promoted to the home page or rank highly on the site. I wonder how the model skews these results.
Quantcast chart comparing unique visitors between del.icio.us, digg, and StumbleUpon.
