Tanne tells me new features include:
Collections – Wink Collections are a cool way for you to gather and share the best links on any topic. A collection can be about anything – hilarious videos, your favorite band, the best restaurants in your area, or research on a new gadget – you name it. You create a collection and add links to it and it shows up in search results.
Others can add links to the Collection – a great way for people to share what they know and improve search.
