There is a new entrant in the search engine market --
wikia. Jimmy Wales the founder of wikipedia is behind this. The idea is to involve users in creating content for the search. When I entered the key word enterprise architecture, there were no results. The search engine offered me the option to enter an article on it and create new content. In addition, I could create a discussion forum on it. If others have similar interests, their profiles appear on the side. Similar to wikipedia, we will have some issues around the quality of content.
As we were discussing this in class, one of my students pointed me to the Korean search engine naver. They have used a similar
approach to search. Since this is a highly wired country, people have been using this for local navigation and Q&A. In fact they are the dominant search engine with 77% share. While Google has been very good for generic search, it is possible that there is a market for localized search with input coming from users.
