1. Going to look at the recent state of Om/next docs, I see that you're right. I don't think the earlier iterations of the project had quite the same focus but it's clearly been made a higher priority.

2. I think the barrier to starting a new project is unreasonably high, yes, and requires a highly inconvenient amount of configuration familiarity. Unfortunately the gap between just running the ClojureScript compiler on a single namespace file and actually configuring a viable project and build pipeline in Leiningen is quite large and really requires a concerted effort to overcome (or, to have someone nearby who's willing and able to show you what you're doing wrong).
