> The compiled default CSS file weighs in at a comparatively tiny 30k, versus approximately 100k for Bootstrap and almost 200k for Foundation.

At first I was sceptical that this was even close to a fair comparison, however even after stripping Bootstrap back to comparable functionality its CSS still weighs in at 68KB.

I will be watching this project with interest, but I think it probably needs a lot more use before all the edge case bugs (that Bootstrap has probably already dealt with) get ironed out.
