Thanks - we've called it visual search because it basically allows you to go cherry picking by selecting skills or other attributes you're interested in (e.g. active job seeker) from profiles or search results.

Say you're looking for an Ajax developer - you'd start by looking for "ajax" only, then keep clicking on tags until you've found the perfect match - a bit similar to browsing a supermarket's shelves and adding stuff to your basket (that's where the term "visual search" originates from :)

About the link - I'm not sure I can make it clickable...
