James "Jimmy" Wales, founder of the non-profit, online encyclopedia Wikipedia and not yet developed, commercial search engine Wikia, exchanged barbs with Jason Calacanis, founder of Weblogs, Inc. and the recent human search engine Mahalo, over the holiday on the Wikia mailing lists. Wales says that, since it isn't free, Calacanis' Mahalo "is just not that interesting. I mean, I am sure it is lovely and all, but I really don't care about it." Calacanis, not one to shy from a fight, questions Wales' accuracy, memory, ability to hold his liquor, and apparent ambivalence. Calacanis, a constant self-promoter in need of publicity for Mahalo, and Wales, an idealist who can dismiss commercial concerns in favor of an academic debate, both benefit.
