This is a good point - I should clarify: what I mean is that there aren't a lot of tutorials, step-by-steps, etc by people using the systems... the type of thing I think of as "screwing around guides". The IBM documentation always feels more like deep manual. I'm pretty sure that even if I had access, I couldn't be up and running on a mainframe in an hour, like I could with some web stack and a simple app tutorial, there don't seem to be good blogs on "how I managed to do $HOT_TOPIC_OF_THE_WEEK on my mainframe". I find these really important for understanding various other technologies... not as an end to my understanding, but as an entry point. Conversely, If I finally get some time to look at Clojure seriously, I know how to find resources in a simple way. I could very well be wrong about this though. Maybe they exist and I just don't know the ecosystem terminology, but that itself is a problem, I can't even figure out how to get into the ecosystem if it exists.
