This project is some kind of an experiment. The main supposition of the project is that tags specified by blogs' authors in their blog posts are associated between each other. Our tag spider runs over blogs feeds, gathers the set of tags from each blog post and then combines tag pairs from the set of tags. We suppose that pairs of associated tags can have wide applications in science, marketing and IT. We have found several methods of use. Through API you can invent your own methods of use.
"(...) tagging system is not "controlled" in this sense (...), but I'm wondering whether its web-scale nature can provide some benefit that one would not expect."

Search on Spock to find your friends, old acquaintances, your favorite celebrities, or people you would like to meet. With Spock you can discover people by searching for their name, or by using descriptive tags. For example if you type in "NFL Quarterback" into the search box, Spock will pull back a list of people who play quarterback in the National Football League.
