I, like many other developers, really like Twitter's bootstrap framework. However, many of the websites using it look the same or similar (those buttons, that navbar at the top, amongst others). What are a ways to differentiate your website without needing to break out CSS power tools (Acknowledged, design is fundamentally important, but regardless, I am a hacker)
Agreed. You don't want to give up on Bootstrap because it's just so easy to use. My advice would be to spend the $20 or whatever it is on wrapbootstrap and get a decent theme that you can use for rapid prototyping without it looking like the stock Bootstrap theme.
