I've been thinking about memes lately. About the self-propagation of interesting and cool objects or ideas. I read a fair number of diverse blogs - different topics with different geographies and different audiences. Yet I find that they often post the same memes. BoingBoing is one of my favourite meme factories. And Twitter is certainly a meme replicator on steroids!
I saw Susan Blackmore earlier this year at TED and I was entranced by her presentation on memes ... how humans are meme machines ... as well as how temes have evolved - temes = technical memes. Love the ideas in her talk.
