Open Facebook or log in Facebook?

[Mamoun]

What is more proper? :

1- Open Facebook
2- log in Face
3- log into Facebook
or
log in to Facebook

or if there is a better one than what I mentioned

and why ?

I'd be thankful for any help ^_^

"Open Facebook" (or "Open up Facebook") if you're already logged in.
"Log into Facebook" (or "Log in/on to Facebook") if you haven't already logged into it.

Normally, I'd just say "go on facebook".

However, if you're looking for statistics:

"log into" grants 53 million hits, while
"log in to" gives 41.60 million hits.
