What's so special about a Like button?

In a recent article for CNN Tech by Mashable's very own, Pete Cashmore, we learn the Like button on Facebook is so much more than a button! So we know that there are a lot of things we can do on Facebook, but on Twitter, the options appear to be limited to three things: follow, tweet and retweet. However, for a lot of Facebook users (a.k.a. me) who aren't into all those applications, what is the big draw with Facebook? In the article, I have found the answer, the Like button. Ah yes, we like to like things and this button just makes it so easy and NORMAL. For example, if a friend of yours says something to you, don't you wish you could hit a Like button then, but that would be weird, right? You wouldn't say to them, "I like what you just said." On Facebook, "liking" things is beyond normal, it's a part of our daily routines! I think the like button makes the whole entire Facebook experience more personal and more interactive; it basically lets Facebook users know that they have a voice amongst Facebook users. If you tell me that you have never "liked" a friend's status or a facebook page, I just know you are lying! Ok fine, were you at least tempted to hit the like button?
