Some niche site ideas are so unusual that they stand out immediately. A niche site means a website that focuses on one very specific topic, sometimes so specific that it surprises people. Examples can include sites about unusual pets, strange collections, or very narrow hobbies. There have been sites about nothing but rubber ducks, different types of garden gnomes, or even reviewing only one type of snack food. These sites often make people curious because they seem too narrow to attract an audience, yet some still manage to grow. Sometimes the more unusual the idea, the more attention it can get. What are some of the strangest niche websites others have come across? Do you think unique topics like these can actually succeed, or do they usually fade quickly?
