pete.com says Delicious gets about 2 million unique visitors a month and has stopped growing. Twine just passed 1 million uniques and is growing fast. Spivack said that 40% of that traffic comes from Google, and sure enough those Twine pages look awfully juicy from a spider's perspective. Spivack expects Twine to hit 2 million uniques in a matter of months and that looks like a credible claim to us.

"Common Tag is an open tagging format developed to make content more connected, discoverable and engaging. Unlike free-text tags, Common Tags are references to unique, well-defined concepts, complete with metadata and their own URLs. With Common Tag, site owners can more easily create topic hubs, cross-promote their content, and enrich their pages with free data, images and widgets."
