Why do people Facebook?
I facebook because my kids neither text, email, nor call. They do facebook. Therefore, I must or remain out of the loop.
It also has allowed me to reconnect with some people who live far away and are from a time long ago. I enjoy that.
And the mark of the beast will similarly be accepted. It will be convenient
Apollo astronaut Buzz Aldrin once said something along the lines of, I imagined we would have colonies on Mars by now but we have facebook instead.
