I had assumed that "Datomic in the browser" meant an implementation of Datomic that actually runs in the browser (presumably written in ClojureScript, though not necessarily). In fact, this looks more like "[Accessing] Datomic from the browser". Aside from that, this does look genuinely interesting. I'd like to see more information about how people are using Datomic - I've evaluated it briefly but never saw a good enough reason to move away from familiar relational databases.
