Issue #24: Polymorphic Discrimination Smell

public IList<BlogComment> Comments { get; set; } // No way to distinguish types

Hidden Problem:

• Prevents future comment types (e.g., ModeratedComment, AnonymousComment)
• Forces type checking with is/as operators
• Violates Open/Closed Principle

Advanced Solution:

classDiagram
    class BlogComment{
        <<abstract>>
        +Id
        +CreatedDate
    }
    
    class UserComment{
        +UserName
        +EditText()
    }
    
    class SystemComment{
        +SourceSystem
    }
    
    BlogComment <|-- UserComment
    BlogComment <|-- SystemComment
