I've come up with a few ideas for maintaining the community experience on the sift while reinforcing quality control:

• Write a blog post about a member's best videos -- Verbose bookmarks!


• Write a topical video blog using old sifts -- Annotated playlists!


• Write a review of several queued or pqueued videos


• Cross-linking: Relate similar posts and content in your video descriptions

It's becoming clear that it will take some effort to keep the art of sifting above the level of watch, rinse, and repeat.
I've kept this short because I want to hear your ideas for keeping the Quality of the Sift up.
