We've been on LinkedIn for years and we've still no idea what it's actually for.

Foursquare
Foursquare is finding it hard to make anyone care

Some apps fall into disuse because the novelty wears off, and that's definitely the case with our use of Foursquare: the thrill of seeing that your friends were at the gym or of becoming the mayor of the nearest greasy spoon wore off awfully quickly.

Any developer writing apps for kids that contain £74.99 IAPs needs to take a good long look at themselves.
