This research study aims to evaluate the effectiveness of TaiwanBaseballWiki, established in 2005. First, the researchers collected data and analyzed the web logs from April 14, 2005 to August 19, 2007. A number of statistical measurements were used to analyze the data. The results show that 1. The number of page views has grown by almost 15% per month on average; 74% of page views came from 20% high browsing pages; 2. The registered users has grown by nearly 33% every month on average. It is also found that only 163 users have edited more than 10 times and were accounted for 91% of all the editing. Among them, the most active 1.9% of the users did 80.8% of all the editing; 3. The pages have grown by almost 6.06% per month on average, and only 8.75% of baseball pages had been viewed over 10 times on average. Moreover, the research also adopted the web questionnaire method to understand the community users from different perspective. The result shows that 1. The community users were mostly fans aged 24.8 on average and were young students. This result was the same as what we have previously predicted; 2.64% of respondents were unregistered users, and among them 40% stayed unregistered because they only needed a quick search for some information; 3.34% of them have edited website pages, and among them, 41% are active participants who have edited more than 1000 times and 45% of them started editing after using the website for one week. Finally, the suggestions for the website, as the results of the evaluation, are to promote baseball history pages, promote low viewing pages, design a user-friendly interface, and design new website styles suitable for young users.
