Aside from reading typed replies to any given post it is a way to gauge how the community that didn't type out a response feels about the post. IMHO they are generally two different groups of members with only a little crossover.
OK. I'll have to trust your ability to gauge that. I don't have that ability.
My question was looking for something a little deeper. For example, suppose someone subscribes to a service that tells them, with a 60% probability, how many clouds were in the sky at 10 PM on the previous day. I ask them what value they get from that. They answer that it tells them how many clouds were in the sky and they want to know that.
There are two problems here. One, they believe they've been told how many clouds were in the sky. They weren't; they were given a count with a probability. So they're being mislead. Two, unless it's just some kind of personal pleasure knowing how many clouds were in the sky, they haven't explained what value that information has for them.
If they were to explain that they have a statistical model that predicts hurricanes based on cloud counts, then I would understand the value.
Like the misunderstood cloud count, a thumbs down is also likely to mislead a reader. If I see a post with a single thumbs down, that's so little data for me to gauge anything about the community; I have no idea what the person's problem with the post was. Also, I almost never research the person who had the reaction. I have no idea if they're a regular or just a new visitor. I have no idea if they can reason well. Maybe they're just having a bad day. To be honest, if I see you or
@belvdr giving a thumbs down, I'd give it more weight than a thumbs down from someone I don't recognize. But for the most part, I don't recognize or even notice the names of the people having reactions.
If I see a bunch of negative reactions, I still don't know what to conclude about how the community feels about the post. Are some of the disagreeing and others disliking? What parts of the post are they disliking since each person could be disliking different aspects of it.
I gotta say, if I dislike a post, I get pleasure when I see people giving it a negative reaction. If I like the post, I generally discount the reaction or think less of the person giving it. I don't think I'm healthy in this.
If I disagree with a post and I see a negative reaction, my beliefs are reenforced. That is dangerous. They might not share my beliefs and be disagreeing about something entirely different. I've really learned nothing, but I've been pushed into a more intransigent state.
My comments seem to apply to all the reactions, not just the thumbs down.
One of my posts above got an angry reaction. I have no idea what the person was angry about since I made a few points. Actually, I was the one having a bad day when I made the post; the thread on Brazil was making me very upset. My post had more emotion than I usually allow. It would have helped me to have received a reasoned response. But instead, MacRumors got the benefit of increased user engagement at my expense.
