I don't care whether something is in one area or another, I only ever look at http://www.se23.com/forum/search.php?action=getnew
which provides the latest postings from all sub-forums. Some of the longest threads (including Lewisham A&E have occurred in Wider Topics).
Perhaps we just need more people to post about subjects that interest them. Unfortunately I'm so narrow minded I rarely think about anything beyond SE23.
