How exactly does the "trending topics" sidebar work?
I'm asking because right now the top 3 are "Assurance Wireless", "Angry Birds" and "Samsung Infuse 4G". Clicking on these reveals that the first 2 have no threads whatsoever to display, and the third has had no posts in the last fortnight.
Just curious. I ignore this sidebar anyway, but it seemed not merely pointless but perverse that there should be a "trending" sidebar that takes you to sections where there is no discussion at all happening, and I don't see this giving a good impression to new visitors.
