The reports of its death were greatly exaggerated.
What’s a Stack? The site explains that these playlists for the web are collections of links:
built around a common theme. To get started, visit the stack tab on your profile page and click “create stack.” Choose at least three links, add juicy descriptions, pick the best images, choose the layout, and shuffle the order of links. When you’re all set, click publish to share your Delicious stack.
Just as folks were able to browse the bookmarks of others, they may now also browse for and follow the curation efforts of Delicious Stack creators.
The new Delicious also allows phrase tagging.
It may take a while for the Stacks community to reach critical mass as a search tool, but it is growing surprisingly fast. I hope to introduce it to my kiddos next week, along with a few other attractive, media-rich options, for curating senior project research.
