Do you find it hard to concentrate on your work and can't stop surfing the net when you should be doing something more constructive? Well now there's a solution.
According to an article in The Wired Campus, Apple users can download a shareware application called Freedom that blocks your net access for as long as you want. So if you need to concentrate on writing that research paper or report and do not want to be tempted to check the latest sports results or what your friends are doing on Facebook, then you just activate this and you're on your own. Once you've enabled the net-blocker you can't disable it until the blockage time is out (unless you completely reboot of course, but that takes time).
I don't think this will be a massive success but the mere idea that someone has produced a tool like this must say something about homo zapiens. The distractions of the net are rather compulsive.
