Nature is trying out an idea that Deepak Singh loves. There's a wiki accompanying Lincoln Stein's new paper in Nature Reviews Genetics. (The review discusses biological cyberinfrastructure and is also worth a look.) The sections of the wiki include the major themes of the paper such as centralized online databases and analysis systems, bioinformatics toolkits, the semantic web, and more. "I'd argue that something like this should accompany other types of papers," writes Singh. "Too often people publish papers with incremental improvements. Perhaps they could avoid doing that and update a companion wiki or something along those lines."
