Mashable is a unique tech success story. It is a media brand name, true, but it is essentially a tech startup gone large. I was just thinking Mashable's unique three different size columns, ample use of white background, and infinite scrolling seems to make for infinite real estate. You show up to read one article and you end up reading many headlines and few more articles. It is very well designed. Mashable has made better use of real estate than Facebook itself.
