To many people, Facebook is the default communication channel

Exactly. Many of us geeks have dreamed of improved e-mail clients, better to-do lists... but frankly for the average person, they want to hear from their kids and relatives, easily see pictures of birthdays.

Come up with a better client if you want to, but understand that some people have "simple" needs and your decade-old technology (what has changed since UUCP?) gets in the way.
