Try Me virus

Try Me virus
 n.— «I suspect Second Life is largely a “Try Me” virus, where reports of a strange and wonderful new thing draw the masses to log in and try it, but whose ability to retain anything but a fraction of those users is limited. The pattern of a Try Me virus is a rapid spread of first time users, most of whom drop out quickly, with most of the dropouts becoming immune to later use. Pointcast was a Try Me virus, as was LambdaMOO, the experiment that Second Life most closely resembles.» —“A story too good to check” by Clay Shirky Valleywag Dec. 12, 2006.
