Burke and Kraut have undertaken this research to broadly examine the development of interpersonal relationships based on interaction over social networking sites (such as Facebook) with friends. It also seeks to explore the impact such sites have on relationships offline through a sample survey of 3,649 Facebook users with 26,134 friends. The primary intent behind this research is to understand if these sites have any adverse impact on existing relationships or simply replace them with newfangled, virtual friendships. The effects are measured through types and intensity of communication in social networking jargon such as likes, comments, and posts.

The survey was conducted to understand the strength of relationships based on communication, frequency, and relationship types. This strength was measured and compared with traditional communication methods such as intimacy, exchanges off of social networks over phone, e-mail, and so on, and types of relationships (friends, colleagues, and so on).

The survey analyzed behavioral log data by examining users’ direct communication, broadcasting, and passive consumption. A few examples are provided on their positive impact in cementing old relationships that were seemingly jeopardized, as well as building new relationships with strangers via Facebook who later became familiar entities after a personal meeting.

The study concludes with the types of Facebook interactions that are positive and build bonds among virtual or real friends over a period of time. Although the strength increases with broadcasting, more strength is provided by direct and composed communication.

However, the study does not include following criteria:

1. On a negative note: Friendships may turn bitter following unpleasant arguments over deep-rooted religious or political affiliations or views.

2. On a positive note: The study doesn’t include relationships developed with unknown like-minded users promoting the same cause.
