Here is an idea that would make the Developer Community immensely more valuable (to me anyway)
Have the capability of getting Listing output from searches or tags or groups.
In addition, have people put titles on their answers and comments,
And having a detailed list with all the answers and comments if needed
Then being able to sort the list by date or other criteria.
Something like:
Sub1 . . . .
-answer . . .
-comment . .
-answer . . .
Subject2 . . .
-answer . . .
Subject 3 . . .
-comments . . .
