The view itself (except for stickies) is in newest to Last order. So you are seeing all of the threads with Posts. Since it shows the date of the Last post also you can tell when to quit looking at them.
At the main forum entrance
http://www.shrapnelgames.com/cgi-bin/ultimatebb.cgi there is a button to show "Todays Active Topics". SEIV or Dominions amounts to most of the Posts so it wouldnt end up being too cluttered.
In your profile you can change your settings for how many days of traffic you want to see. 1, 2, 5, 10 whatever. I think it defaults to something like 45 days worth. Im not sure. I set mine for 2 days a long time ago
Hmmm thats all the options I can think of.
