StumbleUpon now have introduced to public new service StumbleVideo which can ease you to search videos you want. As the Internet video now is on the wave I think StumbleUpon want to take their part of the pie.
The idea of StumbleVideo is very similar to StumbleUpon – watch the videos and rate positive or negative if you like it or not. Ratings are used to search for videos you might like. It also show other users which liked this clip. StumbleVideo offer also opportunity to search videos using channels like sports, music, art atc. Option that is very helpful is history tab, where you can see previously watched videos.
At the moment video sources where StumbleVideo search for the videos is MySpace Video, Google Video and YouTube and this means that the range of videos is very wide. I was testing the StumbleVideo before I wrote this article and one thing I can tell for sure – take couple free hours! 🙂
