Facebook: Like Button v/s Wall Post Like

Question

I just went through this nice Like button documentation .

As per my understanding the Like button is used on a website and when the user clicks the Like button on website, a story appears in the user's friends' News Feed with a link back to your website.

So is this Like button same as the Like button that is present to very Wall posting. What i mean is whenever an activity is posted to Users wall it has the default Like button and comment button too. Are these two likes same?

Also if i want my application to find out which user clicked the like on the wall posting, can it be done? Please Correct me if the question is inappropriate or incorrect.

Answer 1

When a user clicks 'Like' then an edge is created between him and the liked object on the fb graph, regardless of where the action was made.

The app has nothing to do with this process, the user liked a post on a wall, why would it "connect the app and the wall post"?

Check out the Like fql table which can be used to return the IDs of users who like a given object (video, note, link, photo, or album)

Answer 2

Refer to the FAQ'S in the facebook documentation for the like button, to know which user has clicked the 'like' button.

What analytics are available about the Like button?

If you visit facebook.com/insights and register your domain, you can see the number of likes on your domain each day and the demographics of who is clicking the Like button.
