In the recent past, I've begun looking at Twitter and Facebook. For a while, I've used (and am frequently quite amazed) at the internet.
I just read an article about the transition from the Pony Express to the Telegraph to the Telephone, Internet, FB, and Twitter.
Alexander Graham Bell (years after the telephone was more-widespread) refused to have one in his office. Oh, and Western Union refused to buy Bell's patent at $100,000 as it was just a toy.
I wonder what we'll look back at and just roll our eyes at.
