Love the layout, the simplicity. Just a few errors from what I can see quickly going over it, but they seems to be relatively quick fixes. Great work. I could definitely see myself playing around with this base and using this for projects.
I'm still on the fence whether or not I want to share the theme. There is a lot of maintenance involved since it modifies a ton of core templates, but if the interest is there perhaps I'll consider it.
This one was a labor of love. Theme development is not something I'm interested in, but tweaking your own site is often the exception.
