The common meaning of multi-tasking is doing more than one thing at once, like walking and chewing gum. Do you hold several conversations at the same time—on the phone, on Facebook and in person? Do you listen to music or the radio or watch TV or eat lunch while you check your favourite blogs and watch your auctions on eBay? Do you have several work projects on the go, spread across your real and virtual desktops? Is it hard to keep track?
Technology usually helps us function by making daily tasks easier, safer, more efficient, and so on. But sometimes a technology comes along that doesn't simply improve the way we do something, it actually creates a new type of behaviour. I think this is the case with online social networking, which allows individuals to broadcast to mass audiences in a way that wasn't available in the past. The question remains, however, as to whether this activity makes life any easier! Some have certainly found it just causes them trouble.
Is your boss or co-worker getting on your nerves? Are you irritated with your neighbour? Do you feel like venting out by writing some nasty stuff about them on Twitter or on a blog? If you do it anonymously, no harm done, right?
