For those of you that have been here a long time, there is no doubt about it, you can see the change with the addition of the "like" button. And now we get a score? A reaction score? These things are there for one purpose and one purpose only. Drama. "Like" buttons were not created to make people feel better, the were created to make people feel worse when they don't get a "like". It makes people want to post more, so they can get more "likes", so they can go back to feeling how they felt before they made a post that didn't get any "likes". Not to make them feel better, just to make them feel as good as they felt before. Many many people live for "likes" from people they don't know and never will.
Just a thought, I could be completely off base, but the timing is spot on. ...............oh boy, I hope I get a "like" out of this.
