At time, I guess some members scroll back months and read discussions here.  Thats great.  I have also noticed that some respond to posts that are months old. That means, they are burried deep in the discussion board.  Some peeps may respond to dozens of old posts. I know, cuzzz CAT and I approve them.

Chances are most will not page back that far so if you want a response to something you may have posted or you are responding with good input, you may want to just create a new thread.

Hope this helps.
