I don't mind the prediction threads too much, and I will even participate in the discussion every now and then. But I hate when we all give our 2 cents and we never get an update. Why should we tell you if we can't expect to hear how it ends up?
So if you've ever posted a "Predict my ___ time" thread or a "What can I run for ___ given this workout", please go search for it and let us know how it turned out.
