Just an idea:
Use of modules is required to do particular task. If you juggle between 2 modules, you can always say that for doing task T, module A (is better|same as|faster|efficient|..) than module B. You can build the fact list. These facts could be changed over the period as new Modules are introduced. Group specific modules (for example : Date/Time) could serve purpose here. These has to be maintained well. We may start something like that over here as a new section. The knowledge which is shared in form of SOPW or Q&A answeres can be given a systematic format where only module(s) are answers to your question (not regex for example), much similar to c.p.l.m(o)
