Mahalo is monetized through Adsense(well some affiliate links too). + the fact that the result is usually incomplete, means people are more likely to hit an ad to find a better answer.<p>So it's most likely a big cash cow for Google.<p>Which do you think it's better for them to send a user to? Mahalo powered by Adsense or __________ powered by Tribal Fusion?<p>Oh and just to clarify I'm not saying Google is doing anything evil. They don't adjust their algos to help push Adsense sites higher. But when an adsense site reaches the #1 position, they do appreciate the extra revenue.
