I always knew that one day there would be a digital craze that would sweep the nation, but leave me at a loss. Foursquare is that craze.

I know a lot of people struggle to see the point of Twitter. But at least at its core it is a communication platform. There is plenty of scope to say something interesting on Twitter.

But what is Foursquare about?

Oooh, look at me – I’m having my lunch!

Oooh, look at me – I’m at a fancy bar!

Oooh, look at me – I’m in a posh restaurant!

I might get it if it wasn’t such a laborious process to have to check-in somewhere. If it was a matter of one button press, I would probably do it. But it takes ages to do it. What a faff! Maybe the fancy bar isn’t so interesting after all…

Now that Facebook Places has launched, this sort of thing will probably get a lot more common. But what does it add to the world?
