What are memes?
In a discussion with two scientist friends tonight, they happened to talk about memes in physics and I finally had an idea what the word 'meme' meant! They called it a "cultural idea that is repeated and passed on." That seems to encompass some of the qualities of blogger memes.
Wikipedia actually has quite a comprehensive article on memes, as does this site. Here's another great site that explains more about memes and their importance. Fascinating!
Anyway, I'm glad I now know the origin and meaning of the word 'meme'. I never quite like using a word and not knowing what it means!
