Sure, I didn't spend a lot of time with it, why should I? I saw that it was missing a great deal of basic things out of the box. I decided quickly to not waste my time learning more esoteric stuff that is only useful if I stick with Joyent and SmartOS.
You are an absolute genius for creating dtrace and it is nice to have but certainly isn't a necessity for most applications. Your example is voxer which is a total edge case since they've been pushing the node envelope since day one.
In the end, the reality is that SmartOS doesn't feel modern at all, it feels like Windows98. Actually, it feels like SunOS back when I had pizza boxes under my desk 15 years ago. I could spend time giving you tons of (free) feedback about what's wrong with SmartOS or I could just use Ubuntu and move on.
9900+ concurrent connections on a $22/mo Ubuntu box is 'good enough' for me.
A few days ago there was an article about Linux monoculture. It's even worse than that, it's an Ubuntu monoculture.
If you really believe there is more information in SmartOS' wiki than in man pages & other proper documentation available about Linux, I don't think the problem is with the Linux monoculture, but somewhere else.
More generally, we're definitely committed to making SmartOS the best environment for the modern cloud; I'm sorry that your experience was frustrating, and if you have any additional concrete feedback on what you'd like to see improved, we're all ears. And finally, I know you said that you "don't care" about DTrace, but I just can't help my (biased) self; if you're developing a node.js app, you really should check out some of the things that SmartOS can uniquely do with respect to node:
