Frankly, I'm surprised so many people use it. It's meant more for the drive-by visitor to draw them into the forums than for day-to-day users.
I liked to think of the previous Recent Comments version as "curated" -- because I do use MacRumors in a drive-by way. I'd frequently hit the main page & then refresh for new threads. Also found many, many fascinating threads in categories i wouldn't have thought interesting by just looking at the category titles alone.
