Want a handy guide to the hottest sites on the internet? A list is provided below. But first let's start with a wordy introduction in traditional Serious Journalist style.
The business world today is dominated by astonishingly valuable web companies, many of which are exciting, cutting-edge industries - although they don't actually do anything.
Consider Instagram, recently introduced to me by my daughter. Take a snap of your iPad and this image-handling programme will makes the picture low-res so that it looks like it was taken in the 1960s. You can then show it to your friends, saying: "Look! Here's a picture of my iPad which looks like it was taken in the 1960s! Woohoo!"
That's all it does. The obvious question is: So what use is it?
Important warning: NEVER ask that question. You will be permanently labelled "antediluvian" by everyone in the room aged 25 or younger.
I have the following conversation with my offspring regularly. ME: "Why did you just take a photo of my 1960s photo of Grandma and Instagram it to look like a 1960s photograph?" THEM: "Dad, it's impossible to explain to someone of your age." I then drag my knuckles back to my cave to gnaw on dinosaur bones and howl at the moon.
But as a service to readers, I recently spent quality time with young people to see how they incorporate the internet into their lives. What I learned I hereby put into easily digestible form as An Instant Guide to the Internet.
