THAT is what it is here for. But General Discussion usually has the most DUers viewing posts because all kinds of things are discussed there.
But due to its popularity, you literally have so many threads being generated that "news" can get lost quickly.
Each forum/group has 30 pages of threads before the last thread on page 30 is "archived" and any additional posts to it will not kick the thread to the first page.
Each page has 80 threads so you are literally talking up to 2400 threads within a forum/group at any given time.
And because the threads are generated so quickly in GD, it ends up that the 30 pages only has about 7 days worth of posted threads before the thread goes "bye bye" (for kicking). Some of the lightly trafficked groups still have threads from 2011 and the start of DU3 and may not have even reached 30 pages.
LBN has a strict criteria of timeframe for story publication, source restrictions, and content restrictions that should avoid "opinions/Editorials", "analyses" and "features".
It's all a matter of preference!
