FB is where basically all local social interaction takes place. Restaurants, schools(!), neighborhoods/HOAs, local governments, kids' sports stuff, et c., all treat it as their main platform for communication. These may (may) provide info through other outlets, but they're usually neglected, outdated, and incomplete—you are expected to use Facebook.

I don't even have an account with them, but I have to visit the site all the time. If my wife didn't have an account, I'd have to get one, for the times when it's needed. FB is the Internet, as far as local real-world stuff goes.
