It is easy to find a persons email address on the web these days. A number of firms have developed sophisticated search engines to gather, cross reference, and sort addresses and then put them into a searchable database for clients to access. While these companies do change a subscription fee for the service, the access to current electronic mail addresses of friend and former co-workers can be invaluable. People who master the usage of social networks will have a significant advantage in finding a suitable partner, getting better jobs, and enjoying a better quality of life.
