Is there a mechanism for a poster to follow-up their question with the results of actions taken based on what was learned here? I'm thinking specifically of GM Techniques questions, but I suspect other tags could benefit as well. Many of the "How do I do this?" and "I have this problem..." posts have interesting and creative answers, and I think it would be instructive to get the OP to provide feedback on what was tried and what worked or didn't and why.
If there is no current device for this, perhaps we could either provide a mechanism to add a "Follow-up" section to the post construct in addition to the original "Question" and "Answers" sections, or institute a common practice of returning and amending the original question statement with an "OP's Follow-up" blurb.
I'll confess, while I do in fact believe this would be instructional and improve the usefulness of our posts, sometimes I just want to know "the rest of the story". (I probably watch too many "save my business" reality shows...)
