New York - Internet entrepreneur Jason Calcanis, who founded the now-AOL-owned Weblogs, on Thursday debuted his latest venture, the alpha version of a new online search engine called Mahalo. The service uses a team of 40 expert guides who arrange search results based on relevance, placing the primary results in a "top 7" at the top. Users can also contribute to the search engine's effectiveness by submitting relevant links to various search terms. Mahalo currently counts about 4,000 results pages, based on the most popular search terms, and plans to reach 25,000 by the end of 2008, TechCrunch reported.
