MetaCafe has just added some new features, which revolve around search and site navigation. There's new search functionality for finding channels about your interests, based on your keyword. Additionally, the modified search results now display channel matches along side the regular video matches as well.
This may seem like a minor tweak to the overall search capabilities of the video-sharing network, but in providing channel results as well as video results for each search you do, you're automatically getting several sets of additional groups of related content. Each channel contains a wealth of relevant content, based on your search queries, so this change in Metacafe's search could help you discover more clips in a pseudo-recommended way.
