I do like these frameworks. Far more sites should use one of those or the principle behind them. My page [1] uses concrete [2] and has a page load of 125kb (including my picture) and loads in less than one second. I don't need all that bloat that comes with a lot of pages (checkout wired.com for a negative example).
The cards of this one look neat, but in case I need something like that I would add it myself to concrete. Nice place to start never the less.
