What is Joel Katz' role in Ripple? I see quite a few answers from Joel Katz, and a friend of mine referred to him as "a Ripple founder". Is this true? His name is not mentioned on this question.
"JoelKatz" is the bitcointalk.org handle of David Schwartz. He answered the linked question and referred to himself as "myself", and you should see him listed under this name as a Ripple developer in other places.
