Ziggs, A Search Engine for Professional's Profiles

I just learned about Ziggs, a search engine of professional’s Web profiles.
Search by first and last name, country, state/province, city, company, and keywords. Results list the individual’s name, location and company. The name appears as a link which directs you to the person’s profile available on the Web.
There are a little over a million profiles in Ziggs, but according to ResearchBuzz, the site is expected to double to two million profiles in the next 100 days.
