问答题In the early to mid-1990s, up to 80% of all Internet traffic was adult-related. Even today, the adult-entertainment industry still drives the Internet, with profit margins of 30% or more, even though they have no off-line revenue stream generated by magazines, books, videocassettes, etc. But in the past couple of years, cybersex has moved uptown. From time to time, we need an expert. In such situations, the Internet has been like a gift from the gods. In the old days, authorities were near at hand for expert advice: the village seamstress on how to make a button hole, the blacksmith on how to take care of a horse hooves, etc. On the Internet, advice and answer sites are popping up all over the place with self-proclaimed experts at the ready. It’s said that expert sites or knowledge networks represent the latest stage in the Internet’s evolution, a “democratization of expertise.” However, if your question is about something other than “Who invented the light bulb?” the answers are likely to be a wild potpourri of personal opinions.
