I was shocked to see on the LiveJournal site that the vast majority of bloggers on that free-to-use, open source system are between the ages of 15 and 23.
The number of bloggers aged over 50 is tiny.
That can't be down to technical incompetence. People of 50 grew up with cassette recorders and VCRs. The have probably been using computers for 20 years or more.
They've almost certainly had a mobile phone of increasing complexity for ten years.
And it can't be that they have nothing to say!
The over 40s must have persuaded themselves that there is something complicated or nerdy about blogging.
The statistics on the LiveJournal site show that the geographic distribution of bloggers is wide. So it's not cultural, either.
Why do you think? Why aren't people who with luck will have another thirty years of life in the digital age, during which all the books, movies and music in the world will be stored and often made online, finding it easy?
