Your reasons for lurking are very similar to mine, in particular the part about being too late to offer anything original. Many times, by the time I read a thread, all I can add to the existing responses is a simple "I agree" or "Yup." And I struggle with pulling off online humor as well.

Also, I too am surprised by the response to a thread that, by definition, should have been the shortest in the forum. I'm glad you posted, though. I enjoyed the read.
