The DjangoGirls tutorial uses a few components of Bootstrap. Mostly for the grid, glyphicons, and css basics, but it doesn't go into much detail. You really can only fit so much into a one day workshop, so they cover just enough to build your blog and whet your appetite for more.
This weekend, I finally figured out how to change my header to a navbar using Boostrap! Its been on my list of things to learn ever since I added the "about" and "contact" pages, which are linked in the header/navbar. I am really happy with how it turned out, even though it looks almost exactly the same to anyone viewing the site. :)
