A lot of questions on this sight are very compelling to parents ( at least me ) who may be in a similar situation that another person has already completed.
I have no idea how this would work, but it would be awesome if somehow there was the ability to follow up / share results.
The best thing about StackExchange sites is the structural integrity of the format, and I wouldn't want to mess with that, so it would have to be well thought out - but if there was some mechanism that rewarded sharing results, I think it could be a real boon for later viewers.
This seems especially important on this site, but would probably provide value on any of the SE sites - or at least most.
Right now I think the closest opportunity to do this is the comments, but they don't have the same impact (I assume by design) as the questions and answers.
