Not really an answer, but a comment. My nickname is yedda, and has been since 1997. It came about pretty much the same way. I was a very wordy individual in English class in Junior High, and would give long, drawn-out answers to any question. I was first called Yadda Yadda Yadda, but this was eventually shortened/altered to Yedda, the hebrew word for knowledge. I was a little surprised to stumble onto this site.
