Mahalo CEO Jason Calacanis is an entrepreneur now, but back in the 1990s, he ran a publication called Silicon Alley Reporter. And sometimes, his journalist roots show. Like during this recent interview with The Deal when Calacanis explained who uses Mahalo. Seems 80 percent come from one place and 80 percent from another. Watch for when reporter Mary Kathleen Flynn nods in a big way, as if to say, "Makes perfect sense to me."

When people come to the site, I think its it's probably 80 percent the use case of Wikipedia and 80 percent the use case of a traditional search engine like Yahoo or Google.
