Meme
This is because I wondered about the actual meaning of "meme".
The term and concept of meme (pronounced in IPA; from the Greek word μνήμη for 'memory') is a neologism that first appeared in the 1976 book by Richard Dawkins, The Selfish Gene. Though Dawkins defined the meme as "a unit of cultural transmission, or a unit of imitation," memeticists vary in their definitions of meme. The lack of a consistent, rigorous and precise definition of a meme remains one of the principal criticisms leveled at memetics, the study of memes.
On a more information technology relation, a meme may also be an idea, project, statement or even a question that is posted by one blog and responded to by other blogs. Although the term encompasses much of the natural flow of communication in the Blogosphere, there are active bloggers and blog sites that are dedicated to the creation of memes on a regular basis.
In other words, "meme" may be called "the new 'aol'"...
