I haven't logged into facebook for over 2 years, but I'm super shocked that I haven't gotten a single message from there.
Really two years is a long time. Have you even told people about that vacation you took?
I don't want to update my Facebook to tell anyone.
Why are you surprised that you have zero messages? Nobody is going to send messages to somebody that isn't using the service.
Well Facebook is buggy. Even if I click like it won't update my likes. My friends have complained about it too.
You have to be logged in to officially 'like' things. Try going to Facebook and logging in if you really want to use it for messages and likes.
