EntreWiki was just launched couple days ago. It's a new Web 2.0 Business Directory of Business Ideas and Opportunities. We are trying to start a new fad of directories using Web2.0 Technologies such as Wikis, Blogs, and RSS Feeds. If you are interested in making such a directory, you can check out zedomax.net where we offer some services to set it up. Check it out here: http://EntreWiki.com
