I have went through this theme and it certainly shows all the love and effort that Justin Tadlock has put into it. Hats Off and Kudos!!
Thank you Justin. Great job.
Great functionality, and also looks pretty good right out of the box. (But browse the child themes if the colors aren't to your taste.) Kudos to Justin for taking the needs of "DIY Joe" into consideration and putting the more gnarly code in sub-folders. This one is fun to mess around with.
