One of the best features about the original iPods was that they continuously tracked the songs that you listened to most, letting you view this chart in a playlist. It was a bit of an eye-opener, especially for “muso” types, when what you thought would be a list dominated by Nirvana, Zeppelin and The Who ended up being won by Abba’s Dancing Queen, with the Cocktail soundtrack bringing up the rear.
It was a great leveller, and reminded us that what we think about ourselves, especially in the ways that we behave, is often very different to the reality. And the same is often true with social media. Do other people see you in the same way that you see yourself? What about Twitter? Do you really know what you tweet?
