Our motives may never become pure, but like river on stone our selfishness is worn down by the generosity of the web. You're good at something and you give away your expertise at length online, and you see people improve themselves and grow happy as a result. In an atmosphere of generosity, bonds grow strong over time, and in a crisis someone stands by you and makes all the difference. Approached in the right way, the web becomes a spiritual exercise of a very upbeat kind. When it comes to giving, what goes around comes around.
