Well here is an interesting thing in town. If you try to be over-social keeping up with your friends and liking everyone of their post then here is a relief for you. You can now simply like all the posts on your wall by just clicking a simple button on your Chrome.
All you need to do is to Goto this site and install this Extension:
A quick and easy way to like every comment or status on your current Facebook page. One click and everything is 'Liked' for you.
--It is currently in beta. If it doesn't work just reload the current page and press the button again. I am still trying to work out some kinks in the extension. -- Like every comment on the current Facebook page with just one click. No need to click every "like" button by itself, now you can click them all at once.
