Social media like Facebook has revolutionized information spread.
It shifts from "one-to-many" broadcasts to "many-to-many" flows, making consumers into creators.
Build a network that shares your posts plus theirs, expanding reach beyond direct followers.
Example: Post a wire jewelry sale on Facebook followers see it, and their friends do too if shared.
"Access" means everyone in this web can read, comment, or share directly, boosting visibility.
