…complexity of
complexities; all is complexity.

Figure 1
Figure 1 shows the distribution of complex-science posters in the rank-frequency representation introduced by Zipf. The discussion list obviously achieved a remarkable success, as is evidenced by the similarity of the posting distribution to Zipfian distribution. However, we should not close our eyes on the fact that the correspondence with Zipf’s law is not perfect. There appears to be a kink around rank 15 with posters above and below that rank following Zipfian distributions with different slopes (see Figure 2).

Fortunately, there is nothing here what can not be fixed. For example, we can stick to the slope dictated by the bottom of the distribution and challenge our top-rank posters to match. The proposed distribution is shown in the Figure 2 by the blue line. To make this happen our most prolific posters should post as specified in the table. The rest of the members of the list should limit their participation to reading those postings.

Although there is not the slightest doubt that our most prolific posters are perfectly capable of the task, alternative approaches are worth exploring. We can stick to the slope dictated by the top-rank posters (magenta line in Figure 2). To make this happen our most prolific posters should abstain from posting and divert their energy into recruiting 6,000 new members.
Also note that we are not bound to extrapolating the top or the bottom of the distribution. We can select an intermediate slope. The most attractive value seems to be 1, because this value of the exponent was envisioned by Zipf himself. The proposed distribution is shown in Figure 2 by the green line. Our most prolific posters should continue to post and in addition 1,300 new members should be recruited.
Now
we need to decide which way to go, make a commitment, see it through, and together
we will achieve a perfect Zipf.
