I see the same words used repeatedly here to describe the user interface for this forum. Words that have no technical association with the operations. Like, clean and light. You're describing your emotional response perhaps, but not an actual operation. When you click a thread title here the same thing happens that happens when you click a thread title in any other forum software. The page changes to display the thread. A new page doesn't load in your browser in a clean or light way, it just loads. Or people describing the experience on their vB forums in comparison to this one as klunky or painful.
The emotional description/reaction to technical things is interesting. To me, anyway.
