Social networking sites such as LinkedIn, MySpace and Facebook are proving a boon for job hunters and recruiters alike, but hirers are being warned not to rely on technology to the detriment of human experience. 

The rise in popularity of social networking sites was highlighted this week with the announcement that MySpace had reached a milestone of 10 million users in the UK alone. 

This surge in uptake has made social networking sites a natural hunting ground for recruitment agencies, as the personal profiles provide ready-made CVs.

Social sites like Bebo and MySpace primarily help people to keep in contact with friends and family, leaving business contacts to the likes of LinkedIn. 

But the social sites have recently been adopted by head-hunters widening their nets in the search for talent.

"More formal business sites like LinkedIn have become useful platforms for job seeking and are a useful tool for recruiters to find new candidates," said Satnam Brar, managing director of ERP recruitment house Maximus. 

"Softer options such as MySpace are largely social and mostly used to keep in touch with friends, but it seems that they are being used more and more for recruitment as well."

Recruitment site Jobtonic launched Refer-o-Matic earlier this week, an add-on for Facebook that allows subscribers to view jobs and make referrals with the opportunity to be rewarded with up to £2,200. 

Refer-o-Matic uses subscribers' personal profiles to display positions in their geographical location.

"By embedding our job vacancies on [Facebook] we ensure that our users have more opportunities to refer jobs to friends and make money if their friends take the job," said Nick Goldstein, general manager of Jobtonic.

Ernst & Young has a Facebook group with over 8,000 members to attract potential candidates, and Accenture has even opened an 'office' in Second Life.
