Robin Good: Redux has recently revamped its curation features especially in the direction of providing a unique platform to curate thematic video channels.
Anyone can easily sign-up, create a custom channel, and add URLs of video clips that they like to add to their video channel.
The TV-like interface REDUX has created is very cool and allows you to watch any channel in full screen mode with clips in your channel that play back-to-back.
You can test out and watch this full screen video channel I have curated exclusively with "curation-related" video content: http://bit.ly/curationtv
Check out the channel content here: http://redux.com/stream/channel/ContentCuration
N.B.: There is not yet a browser bookmarklet that facilitates the clipping of new video content as you browse, the ability to delete a channel, or to scan other video clips to watch as you watch a channel, but these are likely upgrades coming soon.
