Although it is something I think about from time to time, I am sticking to the job I have for a while. I learn a lot on the job and it's a nice place to work.

True. It would be nice if Java had some immutable collection classes that don't have mutable methods. A method that gets a List<String> made with Collections.unmodifiableList(tags), doesn't know that it is actually immutable.

Then it wouldn't be immutable, if I can change the implementation I can also create a mutable version.

Edit example

  public class Article {
      private final String title;
      private final String author;
      private final List<String> tags;

      private Article(String title, String author, List<String> tags) {
          this.title = title;
          this.author = author;
          this.tags = tags;
      }

      public String getTitle() {
          return title;
      }

      public String getAuthor() {
          return author;
      }

      public List<String> getTags() {
          return tags;
      }
  }

  public class MutableArticle extends Article {
      private String title;
      private String author;
      private List<String> tags;

      public MutableArticle() {
          super(null, null, null);
      }

      public String getTitle() {
          return title;
      }

      public void setTitle(String title) {
          this.title = title;
      }

      public String getAuthor() {
          return author;
      }

      public void setAuthor(String author) {
          this.author = author;
      }

      public List<String> getTags() {
          return tags;
      }

      public void setTags(List<String> tags) {
          this.tags = tags;
      }

  }

  public final class Article{
    public final String title;
    public final String author;
    public final List<String> tags;
    public Article(String title, String author, List<String> tags) {
      this.title = title;
      this.author = author;
      this.tags = tags;
    }
  }

[Edit] Changed negative reinforcement to punishment, rbehrends was correct when he pointed out that negative reinforcement is something different.

I don't really know what these numbers are supposed to show. I've shared content that I've later regretted sharing, but it wasn't a lot of regret. If someone had asked me that question in a survey I would have probably answered yes, but it wouldn't really mean anything.

I've also deleted people from my network, but that was because I didn't really care about them. I can't really find any important information in these numbers
