You know you should be working, but these things just won't let you
1 Games
Computer games, by their nature, are generally a bit of a waste of time; they exist to distract you from your boredom. But they can also drag you away from your work too. Of course, if you work in an office, then your employer might have made it impossible for you to install software on your workplace computer. However, if they haven't disabled Flash in your web browser or blocked gaming sites, you can still find plenty of ways to while away your time at sites like Miniclip.com. If only someone would pay you to play Tetris...
2 Facebook
For all its faults, it's hard to deny how addictive Facebook can be. Heard a funny story at work? Then you have to tell all your 'friends' about it. Just imagine how many Likes you'll get! Lovely, ego-boosting Likes... But it's not all just about self-indulgence. It's also about seeing what other people are doing, while you're stuck filing order forms or something tedious like that. Maybe someone has posted something funny that will pick you up. Or maybe someone you secretly don't really like is having a bad day, which will also give you a lift. Whatever the case, this siren is calling you, and it really doesn't want you to get anything done.
3 Twitter
Sometimes, telling people you know (however vaguely) stuff about your life just isn't good enough. Sometimes, you just amaze yourself so much that the whole world should know about it. At those times, you need Twitter. And not only do you get to share the minutiae of your life with potentially millions of people, you can also directly connect with your heroes. Yes, where else can you find the runner-up of Big Brother series 3 repeating something you've written? Nowhere! And the character limit is perfect, because why would you ever want to say something longer than 140 characters?
4 Wikipedia
Although it doesn't have the greatest reputation, Wikipedia is mostly accurate, with the majority of mistakes being of the deliberate kind. It's not good enough for journalists or students to rely on, but for the average Joe, it's a quick and easy way to learn about absolutely anything, whether it be World War II, rare fish, hair loss or anything in between. But it's far too easy to start following links in articles and find you've wasted the last two hours or so - and your boss still wants that report, regardless of how much you now know about the history of Morris dancing.
5 Quizzes
if you were a fruit, which one would you be? That's the kind of thing you can find the answer to if you just complete one of the many short quizzes found on the internet, made up of completely arbitrary and inane questions. These terrible, terrible questionnaires get shared around social networks, and more and more of your acquaintances enlighten you as to which character from Lord or the Rings they are. They're pointless, annoying, stupid and, for some reason, we can't stop doing them. And just so you know, we'd be a mango.
