No zippers? Why then does the official OM docs say "Cursors are conceptually related to functional lenses and zippers". Remember this thread relates to how simple or easy OM is to grok.

And no message channels? Why then does the intermediate tutorial plunge straight into the use of core.async?

I have no problem with OM being considered a grand experiment. I wouldn't use it but it has been an interesting idea generator. Please remember context here - I was responding to someone who claims astonishment that OM could be considered difficult to understand.

But, in terms of grand experiments, let's remember that Reagent came out at exactly the same time as OM. And Hoplon lead the way on Reative (FRP) long before either. So, having lived through it, I'd feel very uncomfortable with any overreaching claims about OM succeeding in inspiring all the others into the alternative MVC holy land. The others were there already.
