Internet is the part of everyone`s life now and most of the internet users have account in social networking sites like Facebook, Twitter & Google Plus. Many people are still not on either of these sites, but they do interact with others via email. If any festive season is there they exchange greetings in the form of e-cards as well. Many times it happens that you get the same greeting card from different people in your inbox as more than one user has chosen the same site to send the greeting card.
