A few days ago, I was talking to my Robotics students about the posts made in our Facebook group. I didn't want to come across as the old guy bashing social media, but I told them I was surprised at how little discussion was actually taking place online. Students would post, but usually others would only respond by "liking." If my students were only posting cat videos, I wouldn't have a problem with people clicking "like" as cat videos lend themselves to that behavior. On the other hand, because most of the posts were intended to start a discussion or get feedback clicking "Like" is less useful, in fact it's often meaningless. Before Facebook and Twitter, if you wanted to engage with somebody's post, the only way (on nearly all platforms) was to make a comment. Writing and posting a comment takes at least a little thought and effort. I'm not saying that "Liking" is bad and everyone should stop it. What I am saying is this: think about what your "like" means. Eric Mack's personal blogOriginally posted on Eric Mack Online
