That's a much tougher question. I am still early in the process, so I don't have a clean and clear answer yet. I am trying to approach FRP from the perspective of GUI design. In this context continuous Behaviors and discrete Events are not exactly what a developer would want to deal with. I don't want to go into it too much now, but I will definitely post my thesis once it is done.
Also, thanks for pointing out the Opera mistake. It is on my to-do list!
I wrote a GUI system using FRP in OCaml. I found events + behaviors (and their Cartesian product) to work very well (with the notable exception that syntactic sugar for defining state machines would be a desirable addition), so I'm very curious to see what improvements you suggest.
By "post my thesis" presumably you mean on your website and not HN? (I'll never find it if it's just on HN.)
