Current students sometimes send me invitations to connect via Linkedin. I view networking as an important component of lawyering. The policy I communicate to students is, "I will accept any Linkedin invitation from a current or former student; don't feel you need to send me a Linkedin invite; I don't accept any other social media invites from current students."
Do you, or does your school, have a different policy? Criticisms of my policy are particularly welcome.
