thrums

Several months back or more there was a humorous post listing the types of replies a post will receive. I wish I had saved it. I want to share it with a friend. It went something like this:

xx% will post an in-depth response
xx% will post a response completely off-topic etc.
xx% will say "I don't know."

I tried to search for it, but could not find it. If you bookmarked it or know where to find it, would you share the location with me.

Thanks!
