I understand that you're probably trying to get Reddit upvotes as well, but I think a link to the repo itself [0] would be better.
And a little critique about your code: you shouldn't set the ivar backing synthesized properties in your implementation (instance) methods. For example, in RDBrowserController.m doing
self.webView = wv
(invoking the setter) rather than
if (webView) [webView release];
webView = wv;
is both shorter and universally safer, and prevents issues if you end up using Key-Value Observing down the road.
It's also safer to retain the new value before releasing the current value in setters you write yourself - this prevents setting to the same value repeatedly from releasing the object prior to retaining it.
