Blog v Wiki

One of the main differences between a blog and a wiki is the fact that a blog is something that has contributions by one person, and that is the person who created the blog. In a wiki you can have many people contributing to the same thing. For example if you know that you are not a good writer you can post something up on a wiki and ask someone to edit it for you by being a contributor to the wiki. A blog can be used as a collaboration even though there may be one person in sole control of it. For example in the reading titled "Brooklyn Blog Helps Lead to Drug Raid", people were putting up posts about what was going on in their neighborhood and other people were posting comments on the blog about other things they noticed which eventually lead to a drug bust. I can't think of anything new to use for a wiki that hasn't been done yet. But much like in the article "The technology popularized by Wikipedia can help companies gather and manage their own collective knowledge. Here's how to get started", I can see it being useful for about any collaborative project.
