How much time have you wasted on Facebook?
We've all asked ourselves and now you can find out - well, get a reasonable estimate.
The aptly titled "How much time have you wasted on Facebook?" app simply asks you to estimate how many minutes a day you spend on the social networking site and then goes through your timeline to the earliest post.
Of course it's only a rough guess and it assumes you've spent the same amount of time every day on the site since you started.
It's also up for debate whether time spent on Facebook is indeed time wasted.
