Networking doesn't end at e-meetings. Stay connected to your contacts by engaging them in conversations that matter but do so with discretion. Don't tag people unnecessarily as it invades their privacy. Don't over post content. You don't want to become a blind spot.
Also, don't forget to give back to your existing network. When someone approaches you for their career advancement, see what you can do. The strongest connections are those where you help people, and they in turn help you grow organically.
So, leave aside your doubts about digital networking and get cracking on that keyboard! It's waiting for you to fire away. Happy networking!
