It turns out that, yes, Facebook is a little like a communicable disease
If you are on Facebook, you have doubtless been battered about the head and shoulders repeatedly by a questionnaire called “25 random things about me.” The idea is that you list said 25 things, forward them to 25 friends, who are instructed to do the same bloody thing. I leave it to you to work out for yourselves whether this pyramid scheme is better or worse that the one perpetrated by Bernie Madoff. In any case here’s an recent article from Slate in which a fellow called Chris Wilson examines the phenomenal evolution and spread of this questionnaire in an entertaining though not altogether rigorous way (despite the fact that he enlists help from a University of Texas professor who tracks the spread of infectious diseases for a living). Nevertheless, you may still glean a few insights about how content spreads virally (dread word) in the online space and how quickly it can peter out.
P.S. Anyone who asks me to list 25 random things about myself will be ignored.
