Some of you may or may have not noticed, but the site is under going change in a number of areas, most notably at the moment in useability and layout:
1. Search page has been totally redone and the "back" button bug that has been there for years has largely been fixed.
2. The main page/content feed was changed some time ago.
3. The browse of topic areas has been totally re-done.
In many places, you will see pages going to a three column format with the middle column being the focal point, things you do with that column on the left, and places/things you might want to go to next on the right.
Much more to come...
