Blog vs. Wiki

       The blog is a web source where people are able to create their own website and posting any kinds of information. We can say a blog is a small community, where people in this community is posting interesting messages onto this community, and allow people to leave comments. The blog is the cheapest way to get your message out to the community. It allows to let people know who you are and allows you to share your own opinion out to your audience. In the article, " Brooklyn Blog Help Lead to Drug Raid", the people who live in the Brooklyn community are using the blog to protect the place where they are living. They use the blog to make the community united together, fight against the drug dealer, and also spread their voice to the outside world to draw the attention.
       In the other hand, the wiki is a website where can allow the contribution from many people for one project. It has all the history stored in the system and can be reverted to if needed. Wiki allow a group of people working on a project, without meeting individually, they are able to edit the project on their own, and the group members are able to review, modify and leave comments on the project. According to the article," More on How to Build Your Wikipedia", it states that the wiki is very good for the departmental project because a large group of people in a different location and different department are able to contribute to the project on wiki easily. Especially when your company is a multinational company, a wiki can connect the companies in different regions of the world. And it helps to determine which software is the best suit your need.
     I think both blog and wiki are useful tools to communicate and spread out your own ideas to the world. I think the wiki can be used as a help station, in which students are able to post their questions on and get help from the professional people in the real world. They were able to either make a change to the problem or leave comments about having to solve the problem.
