Yes, Facebook was designed by Monkeys

Having earlier questioned this based on behaviour of the status update box I can now confirm that Facebook WAS designed by monkeys, having looked at the behaviour of Friends functions.

FOUR links to friends with FIVE different behaviours and no indication of which behaviour to expect.
So:

1. Status updates = mess,
2. Messages = mess,
3. Friends links = mess.

What goes up must come down and I have a hunch that Facebook has peaked.
