Not to mention how social media has also facilitated new relationships.
More than one-third (35 percent) of U.S. adult Internet users have a profile on a social networking site, according to the Pew Internet & American Life Project's daily tracking survey of 2,251 adults.
As more people join social networks like MySpace and Facebook, getting back in touch with old friends and lovers is becoming increasingly easy.
A search on both networks turns up a handful of groups dedicated to lost loves and first loves. Although neither site formally tracks the number of groups dedicated to the topic, MySpace spokeswoman Jamie Schumacher says it's common for users to meet on the site and fall in love and end up together.
