Online presence means interaction. Companies need your identity which you present in different ways, depending on the company, person or context.
You communicate over various channels and
in different contexts but it's always you
“Then the Grinch thought of something he hadn't before! What if Christmas, he thought, doesn't
come from a store. What if Christmas... perhaps... means a little bit more!”
Dr. Seuss
An identity when communicating is not about the channel or the provider, it's about who you are talking to in which context.
Share up to date information
but only as much as you want
Don't be afraid to show your face anymore. Share the information you wish to share to a service provider and be sure your other information is safe.
