We can agree to disagree about Vim and shell scripting. I use those both, all day and every day. Tastes vary. That's fine.
I really wish you would reconsider the single quoting/WYSIWYG/visual divider business. It's extremely jarring to see awk (or sed, etc.) without those single quotes.
Doubting your credentials on the basis of this is silly, and will probably be the minority reaction in the long run. I would be surprised if you don't get offered a few jobs as the result of making TermKit.
