It’s a slower approach, right, because what it means is that people need to move through this process of realizing that sharing information is good，and slowly sharing more and more information over time.But by doing that you get a lot richer information; you get information that people don’t want to share with everyone, but they just want to share with some people around them.You get personal information, like photos from my vacation, or a trip that I want to share with people.And it just ends up being a richer web, and it's more democratically controlled by the people who are sharing stuff, as opposed to by some central entity that’s going out and indexing all this information, right?And that’s the path we’ve been on, and it’s really interesting just watching the rate of information production change.I think at this point there are probably more people who are sharing stuff either privately or semi-privately on social networks (than just letting it be crawled by search engines).When I use that word, I mean sharing with 100 or 1,000 or 10,000 people.It’s not e-mail that you're sending to one or two people，but it’s also not something that you’re making available to everyone.I think there’s a lot of information that people are sharing like that now, and that’s probably growing a lot quicker than the volume of blogs, or other completely open sites on the web.There’s something like a billion new photos a month (on Facebook), and that’s just one type of media on the site (Facebook) where there is over a billion new pieces of information shared each week.
