Recruiters and salespeople are used to paying for LinkedIn, but job seekers probably not. Do they need to upgrade to premium accounts?
Tempting as it may be to upgrade, nobody is saying the regular LinkedIn account is bad. In fact, I believe LinkedIn have purposely made the free accounts good enough to keep building their member base as opposed to charging users. Other platforms like Viadeo and Xing are more inclined to charge their members money and haven’t grown as much.
