Slashdot | A Quantitative Study of How Memes Spread:

"A survey of about 3,000 people who were tagged in a '25 Random Things About Me' note on Facebook found that memes spread through social networks in a remarkably similar way as diseases [CC] [MD] [GC] do. A biologist who looked at the data says that '"25 Things" authors can be seen as "contagious" under what's known as a "susceptible-infected-recovered" model for the spread of disease,' with a propagation factor of 0.27 in this case. But like an infection, the whole thing died out as quickly as it exploded once the number of 'victims' — people who were willing to write 25 things about themselves — was depleted."
