Well, I have came across this very powerful website which enables users to search for anyone in the world using the powerful platform of the Internet.
Introducing Wink, one of the largest search engine that enables you to search for anyone you want. The power of this search engine is that it is also to filter and gives you the most relavant results based on Web 2.0 websites like Facebook, Frienster, Multiply and so on. The search will be based on three criteria which is name, location and interest. With these three criteria correctly and aptly entered, the person you are looking for are just a click away. However, the person you are looking for has to have in some ways participate in online activities like social networking, social bookmarking, blogging or forum for this to work.
Having go through Wink, I found that it is also possible to find out the background of the person that you are looking including details of financial records and so on. But this search only restricted to only people in United States of America.
I find the online people search function really useful because I have used it to find a couple of long lost friends. Because the social networking you are a member of may not necessary allows you to find your friends if they were to join the other social networking websites. This collective search through all the social networking websites is indeed a powerful tool to use.
