Social bookmarking sites are a popular way to store, classify, share and search links through the practice of folksonomy (an Internet-based information retrieval methodology consisting of collaboratively generated, open-ended labels that categorize content such as Web pages, online photographs, and Web links) techniques on the Internet.

Big List of Social Bookmarking and Networking Sites
This list was originally from www.feedbus.com/bookmarks but I've added more to it, and I encourage you to do the same. Vote for the ones you think are great, and use the down-voting for the ones that are no longer operational.
Please note: This is not for people to submit links to their hubs or websites, strictly social bookmarking sites only. I vet all submissions.
