About » Yahoo! User Interface Blog. The Yahoo! User Interface Library (YUI) The New Portals: It’s the Bread, Not the Peanut Butter. This guest post is written by David Sacks, the founder and CEO of new startup Geni.
Previously, he was COO of PayPal. He also produced the movie “Thank You For Smoking.” For the last several years, Yahoo, MSN and AOL have all suffered a declining share of pageviews, but that does not mean the portal is going out of style. Rather it has been redefined, first by Google, and now by Facebook in potentially even more profound ways.
