Also curious what the "I have the same question" link does. Would be great if this was pulled into the Community Manager Reports so we can track popular questions.
I noticed a related thread at How to access the "I also have this question" but similarly no activty since last year.
Along the same lines, what does the "Is this what you were looking for? Yes | No..." link do (shown when you click to a question from search results). It would be really helpful to know if people are clicking this and finding answers without having to ask a new question.
