ok, good explanation. I actually looked it up in "facebook like" on Wikipedia, but didn't find the answer to my question.
Thanks.
Really? The Point of any commercial entity asking for a "LIKE" is this:
-When said company creates a post, everyone who has LIKED the company will see the post.
-If you read the post on you Facebook wall and "LIKE" the post everyone you are friends with on Facebook will see the post.
-Some of these friends who see this post may "LIKE" the company as well. They may even browse their website, purchase something, come into their retail establishment, etc...
-Thus growing your "SOCIAL NETWORK", Client/Potential Client base, etc...
You see it's called "Social Networking" so your posts, entries, offers, pictures, etc... will get out, network and GROW.
