I think you'll end up with primarily new grads in the site with this policy.
If you're employed and discreetly looking for new work and you 'activate' your profile, now everyone in the office knows you're looking to switch jobs.
has anyone yet found a job on linkedin by flipping some flag? just curious. my experience is that linkedin is a source of spam targets for agencies, but i haven't heard of a single case when people were found/contacted by potential employer directly.
