When someone answers my question saying that I need to provide some additional information to better solve my quandry, how should I go about that?
Do I add those details as a comment to their answer or do I add them in the main body of my question?
If I add details only as a comment, then other supporters, those that will be looking through my question, may not notice them. Especially given the fact that some comments are hidden and you can only see them if you click on "Show one more comment".
On the other hand, if I add those details only in the upper section of the page (i.e. that section where the question itself is stated), then those who have already responded to my question and inquired for additional information might stay unaware of the update as many of them, as far as I know, would only return to my question if they are notified by the system of some responses that came as comments directly to their answers.
Of course, I could respond to their comments by adding my own comments to their answers saying something like
I just added some additional details, please look up the question field above
but that may sound a little bit impolite - they have already lost some of their time once when they looked up my question only to find that the description was not comprehensive, and now they are asked to go to that page again and look up those additional details in the upper section.
It seems to me that it would be more practical and, perhaps, more appropriate, if they were able to know those additional details directly from my comments added to their answers as those comments (the first few lines of those comments, actually) will be seen to them in their account's summary page (the one that you get to by clicking the envelope icon right next to your name), and, thus, they will know whether or not they could contribute anything to solving my problem without going to my question page.
And finally, if I add additional details both in the upper section of the page and in all the comments to their answers (and their comments), it will make the page unnecessarily overloaded with redundant information, which will be overwhelming both for me and those who will be reading this page in the future.
