I'm on LinkedIn but mostly just to have my name and profile "out there" and to keep in touch with business acquaintances - I'm not actively seeking a job or anything else.
I got a invitation to connect from someone who works at my company but who I've never met in person or ever had any interactions with. I suspect he may have just searched for people listing the company as their employer and sent invitations to everyone whose name came up in the search.
For those of you with more LinkedIn experience than I have - is this an unusual request? And is it common to accept a request from someone who you have something in common with but who you've never met?
