How many fluther members do you know in real life?

I thought it might be interesting to see how many fluther users the average flutherer knows in the real world.

If you know other fluther users in person…
– Did he/she introduce fluther to you?
– Did you introduce fluther to him/her?
– Did you both find fluther independently and then realize you know each other while participating in the forums?
– Or, have you met in person as a result of fluther?
