A few weeks ago I was pointed to Scitable, part of the Nature media empire. Here's how it's introduced:
A free science library and personal learning tool brought to you by Nature Publishing Group, the world's leading publisher of science. Scitable currently concentrates on genetics, the study of evolution, variation, and the rich complexity of living organisms. As you cultivate your understanding of modern genetics on Scitable, you will explore not only what we know about genetics and the ways it impacts our society, but also the data and evidence that supports our knowledge.
Due to the disciplinary focus I can see why Nature Education might have thought I would be curious. Since I'm rather confused by Facebook's constant barrage of applications the relative simplicity of the interface was a relief. The site has the standard "social networking" features, but these sorts of utilities are useless without content. I clicked Topics, then Population and Quantitative Genetics. This is an area where I feel that Google has problems spanning the gap between Wikipedia and academic articles...because there isn't much content in between in terms of difficulty and depth. So I was curious to see "Shifting Balance Theory" as one of the topics in Scitable. Wikipedia barely has a paragraph. In fact one of the earliest hits on Google for the query "Shifting Balance Theory" is usually a post from my coblogger David at Gene Expression Classic from 2003. And yes, it's still there at the #4 position on Google for me (your results may vary of course!). But Scitable makes it to #5 & #6, pretty good. But what's in the entry?
