we could start from a survey SPA with reagent re-frame or anything group interested, later we could use to vote the topics or dojo etc.

My naive attempt to encapsulate re-frame's implicit app-db, on https://github.com/robertluo/re-frame , it can work now by using re-frame.core/make-app-db macro, which defines reg-sub, subscribe function in same signature with the default one. e.g. by using the macro in your own namespace, you defined these functions by yourself. It maintained 100% compatibility with original ones.
