There is always marketing when people get together. The Internet already has highly popularity, and at the same time user¡¦s online behavior has been changing continuity. We can figure out that social media is the important beginning. In Taiwan, Facebook become the second popular website less than a year, and Plurk make many companies dedicate to marketing just after a summer. There are two target in this research, Facebook and Plurk. After we realize the user online behavior and the situation of online advertisement market,we start to use questionnaire to find out the specific user behavior on Facebook and Plurk. Furthermore, we can also clearly understand user reaction when they see the advertisement on those two social platform, and base on these data to analysis the effectiveness of brands marketing on social media. We proof that kind of social media including facebook and Plurk can satisfy user¡¦s demands of interaction with friends and relax. There are some difference between Facebook and Plurk, so that user also has different reaction when they saw the advertisement on Facebook and Plurk. We suggest that companies can use Facebook¡¦s advantage ¡§diversity¡¨ to set up fans page and find application people like to promote themselves. On the Plurk, we think that brands need to interact with user more personification and always provide useful message to people.

Due to the rise of social networking, people spend more time on the Internet. They not only make friends and express their emotion in the real life, but also in the virtual world. In the stage of the Internet, which without limit in time and space, we can even perform so that other people can spectacle and join us. Hence, through the IT design functions which social network websites offer, how users can perform or spectacle easily on the social network websites, and what the meaning is about the action-dramas which users have performed. A private blog-Plurk, which we also called micro blog, is using as a field of study. In this thesis, we use Ethnography survey to observe and interview the users. We use Coffman¡¦s Dramaturgical approach as the study framework, and divide it into five parts- Front Stage Style, Team Management, Role Play, Impressions Control and Intimate Relationship to analyze. In the data analysis, we compare IT function design and performing dramas. We will find out what the affordance the IT function can offer, and what the drama will perform. Finally, we will sort out the implications of the management and social capital. From this thesis we can learn: 1. What kind of IT functions offer to users on Plurk? 2. Through these IT functions, what kind of action-dramas will perform? 3. What are the implications and meanings of all these action-dramas? This thesis focus on the performing dramas and IT affordance because of the difference between IT function offer and design, the action-dramas will perform quite different, and the IT affordance will facilitate different key point. Therefore, from this thesis we hope that we can figure out some important functions and reasons that people is willing to stay longer on our website and some instructions for the website designers.
