As Dr. J says- we are all experts in something.
Fluther is about a community sharing their knowledge to help others.

What are the more unusual areas of expertise you have?

Are you a history buff? If so what is your favorite era?

What have you studied? Have you studied law, medicine or the arts?

What do you collect? Can you tell us about your collections and why you collect it?

What are your hobbies?

Are you a fan? What are you a fan of? What trivia can you share that we might not know?

Do you have life expertise? Are you a survivor? Have you fought the odds and succeeded?

What is it that you know that you are willing to share with the collective?
