Culture Change Because of the Internet

In 1990, if I used a fact or told a story, I knew exactly where I got it from - which book, which conversation, which magazine (remember magazines?), even years later. I recall reading back then that this had been found to be more common in men than women. I can no longer do this nearly as well. My suspicion is that getting information off the internet involves switching from place to place so much that memory regards that information as less important, and it gets lost in the scramble.
