Blog vs Wiki

           Blog and wiki are identical tools that provide a platform for not only individuals, but also a group of people to communicate to each other.  The difference between them is that the blog is where a single person creates and controls the information, and the other people can comment on it; while the wiki is a place that anybody in the group can edit, add, link, and make changes to it. Basically, the blog is mostly used for sharing, and the wiki is more likely used for coordinating.
          In the article called "Brooklyn Blog Helps Lead to Drug Raid", Michael Wilson wrote a story of how the neighbors share comments about what's happening and what they thought about the drug dealers in the area on the neighborhood's blog, which helps the policemen to investigate and arrest the suspicious quickly. This shows that the blog is being used in a helpful way to improve the security of the community.
          Gardiner Morse illustrated the usefulness of the wiki for the companies in his article "Wikipedia founder Jimmy Wales on making the most of company wikis". The writer stated that within the same company, employees can add their ideas and knowledge on the wiki to improve the company's productivity. The wiki is a fast way to collaborate and communicate, especially when people are far away from each other when they have to discuss some important issues.
           In conclusion, the blog and wiki are pretty similar, but they have their own benefits. The blog is good for the individual, while the wiki is good for a group of people.
