I've been working a lot with node lately as well, there are some things I like but some I miss so much from C# ... there is nothing anywhere near as good as VS for node, and god I miss ReSharper and compilation errors.
On a similar note. I've followed your Playtomic blog a bit and it helped me make the jump to MongoDB for our gamification platform. (We still use SqlServer for lots of things though) Here's to trying new types of kool-aid! :)
Unfortunately there's no reSharper for JS but eh... I feel like it's not as necessary with JS as its a fundamentally simpler language than C#.
