NOTE: The Grouper video share site has been discontinued. It was absorbed by Crackle, which hosts professional videos, but not user videos. If you're looking for somewhere to share your own videos, try one of the top 3 services: YouTube, Metacafe and Break.
Grouper is equipped with a large viewing window that contains thumbnail images of 42 videos that randomly alternate creating a kaleidoscope of entertainment. Whether you’re a producer, an online video buff or both, you’ll feel welcome at Grouper.
The unique kaleidoscope feature, which they call the Video Wall, allows quick browsing; however, some of the images displayed may have questionable content for some users.
After finding a video by keyword or browsing the categories, you can leave a video comment. This is one of our favorites and a feature unique to Grouper. Instead of just writing your comments about a video, you can use a webcam to leave a video comment. This is easily done with the click of a button.
As the name indicates, Grouper uses groups similar to a social networking site. This is a good way to find people all over the world who share similar interests.
