Saket Agarwal, CEO of Spice Digital, a telecom operator company, added: 'A person who does not have access to a cyber cafe or a personal computer is also able to log on to these sites through his or her mobile phone'.

'It's mostly people in the age group of 16-35 who access social networking sites more frequently. The youth today is sporting the best of mobile handsets which enable them to constantly stay in touch with their peer,' Agarwal added.

However, Navjot Kaur, a student, said that accessing these sites from the phone is both impractical and expensive, therefore she prefers to log on to them through the computer.

'I don't like accessing these sites through my mobile phone. For one, there is a space limitation. It is also expensive and I would prefer to log on to these sites, if I had to, on the computer rather than on the mobile phone,' Kaur said.

Talking about the trend, psychologists said since socialising is a major need of human beings, there is a constant urge to find new means of communication.

Psychiatrist Samir Parikh told IANS: 'Whatever forms of communication are available, the youth will tend to use it to stay in touch with their friends. The youth today wants to be a part of the social scenario and would use any means of communication to stay connected whether it is the mobile or the computer.'

However, he added that the youth need to be careful and responsible enough and should use the new technology 'judiciously'.

Gaurav Gupta, another psychologist, cautioned parents to keep a tab on their children's online activities.

'Parents need to be cautious while the kids access these sites on mobile phones because one never knows who they are talking to as when they are on the computer a parent can see what their child is doing. I feel that the youth must be more mature to handle this new technology,' Gupta said.
