Why does Google exist if there is practically unbounded information flow? Oh right, because there is 1) so much information that we can't process it all and 2) sometimes information just doesn't spread. If I host a website but nobody links to it, does the information on my website ever get spread? > If you have a service to file taxes for free, and it really is good, shouldn't it spread by mere word-of-mouth? In an ideal world, yes. But my point was that a service for filing CA state taxes for free already exists, but most people still don't know about it because it's never advertised.
