From the website: Eurekster allows you to build a custom search portal, or "swicki," around any topic of your choice. Rather than returning millions of results like a generic search engine, swickis learn from the search behavior of a community of enthusiasts and experts, making it easy for you to quickly find what you're looking for within a particular topic. In addition, you can easily share a swicki with others and add a swicki buzzcloud to your site or profile ("grab" a swicki), which will dynamically display the hottest searches and give you quick access to that swicki and its community.
