The passing of last week got me to thinking about the importance of paying attention to the visionaries of the world, to those people who think about about the future and try to look beyond the horizon.

Clarke obviously fit the definition of a visionary. He is widely credited with proposing the idea of satellite communications in 1945. The themes of evolution and artificial intelligence that he explored in such stories as and are well worth keeping in mind as our technology becomes ever more powerful and sophisticated.

iPods and DVRs, for example, have fundamentally altered the way in which people receive information by making messages portable and delayable.

I’ve been planning on writing about books that I think are important to Internet marketing folks, so let me mention a few writers I’d suggest to help think about the future:
