Who should you seek out for connections on your LinkedIn account? On the one hand, it is a professional network, and people don’t have to know you personally to be willing to accept your invitation. On the other hand, some people seem to want to connect only because they hope to do business with the other party. The more connections, the better, but you probably don’t want to use sales only for a motive.
