I think that's just further proof that you cannot afford to go on autopilot once you've become successful.

Slashdot wouldn't be slashdot if it had kept growing for the past ten years; there are only so many nerds in the world.

Anyway, Slashdot's icon is still bigger than ycombinator.com's. :)

Think of it this way: Slashdot is the giant's shoulders that Digg and Reddit and HN stand on.
