A while back, a someone I know posted on social media that she was looking for a computer for her 12-year-old son. She posted that she was looking to spend no more that $500, preferably less, and it should be a Windows PC since her son was into playing video games and she preferred a laptop since space in the house was limited. It was a simple enough request that she wanted some input on since she didn't have a lot of buying experience when it came to computers.
One of the first comments made on the post was, "Buy him a Mac, it's better. Windows sucks." I immediately shook my head and knew that no good would come of this. She responded quickly that she knew that Macs were well out of her price range and that the selection of games her son wanted to play was unavailable for the Mac operating system. The commenter was adamant, and continued to badger her that it was worth the extra expense for the reliability and the sacrifice of a few silly kids games. Other people chimed in trying to reason with her friend that she knew what she was looking for and just wanted some brand guidance. He began berating others that they had no idea what they were talking about and he knew best about what she wanted. She ended up deleting the post altogether and reposted to a limited audience instead so as to avoid this particular person.
Herein lies one of my biggest beefs with social media. Just because somebody asks for advice or asks a question does not mean that everyone has to answer it. In the above example, if your only advice is a more expensive, limited capability computer, then scroll past the post and type nothing. That goes for people who respond to posts asking for any Android users having an issue with <app name> since the last update with "I use iPhone, the app works fine for me." That's wonderful for you, isn't it? Except that nobody asked you. Comments like this appear to me to be looking for an argument where there should be none. The original post is looking for Android users and said nothing about iPhone. It happens the other way around as well, and I'm not picking on Apple users, it just happens this way quite a bit more often.
One final group are the unsuitable commenters. These are people who either don't read the original post or just feel the need to insert a comment everywhere. One example of the former was when I had posted an in memoriam for a friend and tagged another friend who had a birthday the same day. The post was saying how birthday friend was responsible for me meeting the deceased friend and was not in any way a birthday post. A friend of the birthday friend comments with a bright and colorful HAPPY BIRTHDAY animated gif. I replied simply with, read the whole post before commenting. She responded by liking my reply and that was it. After an hour, I deleted her comment.
Here's some advice...READ THE POST BEFORE YOU COMMENT! If it refers to something that does not necessitate a joke, please resist the urge to comment with a joke. Don't insert your two cents where it's not wanted, and don't try to start a religious debate over which is the best operating system for a computer.
