In May we talked about how businesses can leverage Delicious stacks to curate their content. In an announcement on July 22nd, Delicious stated that Stacks will be consolidated with Tags starting in early August. According to the statement:
We introduced stacks last year as a visually rich way to think about your links and we've been blown away by the amazing content you've created. But given the upcoming launch of new products from Delicious' parent company, AVOS, and our focus on simplifying the Delicious site, we realized the value of stacks is limited for our users moving forward.
