Here is an actual link to the framework if anyone is interested: http://bluetrip.org/
I use a variant of this, for the sole reason that it provides a reasonably flexible grid system that is very easy to use, keeps everything proportional and consistent, and works in all modern browsers.
I don't enjoy spending lots of time tweaking CSS for each site individually, when I can just throw it on a grid and have it looks great.
It's free? What a deal!
In my opinion CSS isn't that complicated to use a framework, but that still a good thing if people always upgrade other frameworks and merge them to create a more powerful one!
