Okay thanks, that actually clears things up a lot. Funnily enough, I found myself using this exact pattern in ClojureScript yesterday, using a ratom as my store and having what I suppose I should call "actions" which (may make HTTP calls and) update the data.
I haven't used it myself yet, but I'm itching to! I love Reagent and I'm very interested in FRP, especially the proposition that it might simplify the code a great deal if your app is above a certain threshold of complexity.
