But altruism, fun, community and curiosity are also parts of human sociality and I propose that the Web is an existence proof that these capabilities can be amplified, as well.

In October, forestry officials in Zhenping county in northern Shaanxi province published photos of a tiger in a forest setting, saying they were proof of the existence of the South China tiger.

So it's a proof of God's existence that things move in the way they do.
