Twitter, the popular microblogging site, has received increasing attention as a unique communication tool that facilitates electronic word-of-mouth (eWOM). To gain greater insight into this potential, this study investigates how consumers' relationships with brands influence their engagement in retweeting brand messages on Twitter. Data from a survey of 315 Korean consumers who currently follow brands on Twitter show that those who retweet brand messages outscore those who do not on brand identification, brand trust, community commitment, community membership intention, Twitter usage frequency, and total number of postings.

The rapid diffusion of "microblogging" services such as Twitter is ushering in a new era of possibilities for organizations to communicate with and engage their core stakeholders and the general public. To enhance understanding of the communicative functions microblogging serves for organizations, this study examines the Twitter utilization practices of the 100 largest nonprofit organizations in the United States. The analysis reveals there are three key functions of microblogging updates-"information,""community," and "action." Though the informational use of microblogging is extensive, nonprofit organizations are better at using Twitter to strategically engage their stakeholders via dialogic and community-building practices than they have been with traditional websites. The adoption of social media appears to have engendered new paradigms of public engagement.

On January 17, 2001, during the impeachment trial of Philippine President Joseph Estrada, loyalists in the Philippine Congress voted to set aside key evidence against him.

This study examines how information and communication technologies - mobile phone, social networking websites, blogging, instant messaging, and photo sharing - are related to the diversity of people's social networks. We find that a limited set of technologies directly afford diversity, but many indirectly contribute to diversity by supporting participation in traditional settings such as neighborhoods, voluntary groups, religious institutions, and public spaces. Only one internet activity, social networking websites, was related to lower levels of participation in a traditional setting: neighborhoods. However, when direct effects were included, the total influence of social networking services on diversity was positive. We argue that a focus on affordances of new media for networked individualism fails to recognize the continued importance of place for the organization of personal networks: networks, that as a result of the persistent and pervasive nature of some new technologies, may be more diverse than at any time in recent history
