Advertisers often say that people need seven or eight exposures to a new
product in order to really take notice. This is approximately the number of
times I heard about Second Life before I decided to give it a try.
Second Life is a 3-D virtual world
built and owned by its residents. Second Life launched to the public in 2003,
and has grown dramatically since then. Currently, the site has nearly 1.7
million members/inhabitants worldwide.
