Jesus has much to say on generousity and gift giving:
"To everyone that has, more will be given" (Mt 25). Why do they have in the first place? Because they are generous.This is the way Google rates websites and gives favor. Those that give gifts attract hits, and a trail of hits increases google rating, which attracts more hits from other sources, and the website that has most is the same site that is giving most, and it gets even more. So Jesus teachings about giving are very appropriate for understanding the web.
