Many people confuse 'wiki' with Wikipedia, but the world's most popular web encyclopedia is only one of many different types of wiki. They come in all shapes and sizes, but the central theme stays the same: people coming together to collaborate on the sharing of information.
One area where wikis are becoming more popular are game wikis. Strategy guides for games can range from $15 to $30, but game wikis are free. Better yet, they are often kept more up to date than strategy guides and can even have more in-depth information.
Wikis are also catching on in the business world where corporations are putting them to use as a great way to catalog meeting notes, create product documentation and even hold virtual meetings.
