of shorter attention spans - it's just that we've become adept at rapidly filtering what we see, and moving on when we detect dross.
The internet is awash with inconsequential rubbish; anyone with a computer and an Internet connection can go online and write something, and tens of millions of us do it every day. We're doing it here, in this forum, 365 days a year. Some of what's written is interesting and informative, but much of it - my utterances included - is pretty dull stuff. Millions of personal websites are of little interest to anyone except those who publish them, and in general the rest of us pass them by.
Our attention spans are probably as long as they've ever been, it's just that the Internet has taught us that unless we're selective we'll all drown in a vast ocean of words and images.
