Facebook Brings New Homepage and Testing the Menu

First noticed on 29th of June, I thought FB is now trying to copy Google+ as it is testing a new kind of menu floating in the left side, have a look at the snapshot below

And today on 3rd July, I noticed another change on FB's homepage, they've moved the signup form the right to center with a little more styling and bigger button. Also there is a little change in its login form as well, it now feels smooth and better than the previous one.

What do you think?

• Is Facebook really copying Google+? (Menu)
• Does Facebook really needs a call to action for getting people signed up?
