I actually like that homepage. It seems like a nice alternative to tabs, especially if they put useful information in the collapsed tiles (essentially becoming Windows Live Tiles or whatever they're called).
For example, if I haven't been to the site before, I might have to explore the interface a bit before I get to the part of the interface I want. Clicking on those tiles makes things shift and bounce around, the content portion of the screen constantly moves left to right.
Way too much difficulty for doing something so simple.
Designs should be visually appeasing, but not at the expense of ease of use or ease of understanding.
