SELFIE was the Oxford Dictionary's word of the year for 2013, with a claimed 17,000 per cent increase in use between October 2012 and 2013, but have we reached ''peak selfie''?

Apparently not, according to one expert who says we should expect to see more of them.
The act of taking a photo of yourself has never been easier, nor has the ability to share it with the world at the touch of a button. But with the likes of Kevin Rudd and Barack Obama now getting in on the act, the demographic of selfie-takers is expanding as quickly as the phenomenon.
''This activity is promoted from social learning, so if politicians - leaders of the country who represent you to the world - also engage in these kind of activities, it sort of makes people think that it's very normal and it must be something that people are doing,'' Lubna Alam, a social media expert at the University of Canberra, said.
''Because they're doing this, it must be OK for everyone else to do it.''
Ms Alam calls the behaviour ''internet-based self-obsession'' - and said it is not just teenagers who are engaged in it.
''I think this epidemic has surpassed the iGeneration and has moved to Gen X and the middle-aged people who are more and more engaging in social media activities,'' she said. ''It's not just the iGeneration, Generation Y, who are using Facebook; if you look at Facebook and their current user base, it's mostly from 25 to 40 years old … and they're the people, if you like, who are changing their profile pictures every day.''
But as Gen X competes on who can have the best selfie profile picture, the iGeneration seems to have gone a step further and is now competing to take the most unusual selfie.
Be it on a plane wearing the deployed oxygen masks, while dissecting a cat, or any number of the other absurd situations catalogued by the hashtag #SelfieOlympics, the selfie has taken on a new turn.
''That type of behaviour is probably displaying more acceptance of selfies becoming quite normal … as the whole society becomes more self-absorbed in internet-enabled communication,'' Ms Alam said.
But the trend does come with a warning.
''Even though this is becoming quite fun, where our politicians are participating, we still need to remember that in the future these activities can still be found on the internet.''
