Looking to connect with local professionals?
Unlike Facebook and Twitter, LinkedIn is compiled of Connections. Users can invite anyone, whether registered with LinkedIn or not. If an invitee receives too many unsuccessful Connections - their account may end up getting closed. This allows LinkedIn to keep tighter control of unnecessary spamming across their network, and keeps a cleaner platform open for users.
LinkedIn may be the social network suitable for your business-to-business needs. Connect with your vendors and clients via your profile and grow your Connections through meaningful mutual friendships.
