Is the world obsessed with Facebook?

Facebook's active membership now exceeds 500 million users - that's 1 in 13 humans. If it were a country it would be the third largest on earth.

Its usage in Australia accounts for roughly 29% of the time spent online. Based on the average Australian internet user spending around 18.8 hours online each month (as discussed at Social Rabbit), that means, on average, we're spending just under 5.5 hours per month using Facebook, slightly over an hour per week.

With around 10 million Facebook users in Australia that equates to 54,520,000 hours per month, or 2,271,667 days or 6,223.7 people years.

Below are a couple of interesting videos providing more on the Facebook phenomenon.
