I’m struggling a bit with what to do when contacted by someone I don’t know — say on LinkedIn or Melcrum’s Communicators’ Network — asking to add me as a contact.

On LinkedIn, you can and should edit the note sent to include some context (such as “we have this contact in common” or “this contact suggested you and I should connect”), which is helpful.

Communicators’ Network just sends the request, so you are left puzzling out who the person is and why they have your name. The trigger seems to be having a contact in common, which you find out by visiting the person’s profile.

I guess it’s up to you to decide: Do I add all my contact’s contacts to my own network, so mine grows ever larger (and presumably more impressive)? Or do I keep my network generally made up of people I already know or have met (in person or online)? I lean towards the latter.
