The number of posts and the number of posters are increasing. And I would guess, from the second graph, that the 80-20 rule applies: 80% of the posts come from 20% of the visitors (though of course, Roberto had no way of knowing how many lurkers there were).

Peak Science? In the September issue of Discover, Paul Horgan argues that we are reaching the limits of knowledge.

The greatest barrier to future progress in science is its past success. Scientific discovery resembles the exploration of the Earth. The more we know about our planet, the less there is to explore. We have mapped out all the continents, oceans, mountain ranges, and rivers. Every now and then we stumble upon a new species of lemur in an obscure jungle or an exotic bacterium in a deep-sea vent, but at this point we are unlikely to discover something truly astonishing, like dinosaurs dwelling in a secluded cavern. In the same way, scientists are unlikely to discover anything surpassing the Big Bang, quantum mechanics, relativity, natural selection, or genetics.

Just over a century ago, the American historian Henry Adams observed that science accelerates through a positive feedback effect: Knowledge begets more knowledge. This acceleration principle has an intriguing corollary. If science has limits, then it might be moving at maximum speed just before it hits the wall.
