Bootsnipp.com is another twitter bootstrap site that I found on my travels around the internets
It has some nice examples and snippets of code if you are looking for some inspiration for your bootstrap enabled designs, etc
there are lots of examples there that you can take as a starting point for a small job / part of a project,
some of the snippets that caught my eye were the ‘email interface like gmail‘ that could probably be used for any table layout that you want to have (eg for an admin screen showing lots of orders, etc)
another that caught my eye was the ‘admin nav bar with popup sign in‘
I think I might actually use those two in some projects :)
