"Like"

What is it to like something? Is it a desire within a person? Or is it simply a thing to click on Facebook. I vote for the latter however. After all, how difficult is it simply to press down on a mouse button to have the cursor place a little "thumbs up" beside the post. It takes all of what? one second or less. And we are to think that in clicking the 'like' button, that we are somehow adding to the quality of the poster's life simply because we liked it. But what does a 'Like' mean?
That is the underlying question on Facebook. Is it simply just to show support of something? Or simply that you find it interesting? Couldn't you do the same thing in a comment?
People are also perturbed by the lack of a dislike button on Facebook. Why should that be? In comments one could like or dislike the post. Why have we boiled down the enourmous capacity of the English language to communicate into one button exhibiting a "greater-than-neutral" affinity for something.
Becoming a fan of someting makes sense however, with the Facebook pages.  But did you notice that once you are a fan of a page that your update of fan-dage can now be liked? So which truly are you? Do you support it a lot? (i.e. Fan) or do you like the page that you are a fan of? I think that it is understood that if you're a fan of something that you in turn "Like" it.  The 'Liking' of comments within comments which are in posts ought to create a Facebook Parodox, causing the site to form an event horizon, forming a black hole in order to heal the disturbance.
The ambiguity of the "Like Button"is of note. Peple use the button in different ways. To denote interest in a post, to say that they've read a post, or even just to endorse a post which made them smile. I've even seen it used as a way of saying thank you. But I digress. We ought to reconsider our usage of the Like Button. Lest we all turn Facebook into one giant network of Valley Girls. Do you Like it?
