Yes, get MC gets used for a wide array of topics. I typically think about them getting at expectations of complex high dimensional targets and that was my point. My recommendations will be different than others.
I plan to use them to model how things work in our work processes. For example, this was not done as a markov chain, I built a tool years ago that showed how many would be on the waiting list given specific releases. A wide range of factors influenced this, I created it utilizing my understanding of the process and historic data.
But I suspect you could do this a lot better using Markov models. MCMC I already know about and can run. Its not what I am interested in.
