A day after President Obama signed an extension of the Pay As You Earn initiative for student-loan borrowers, he's taking questions from the Tumblr-using public on student debt, college costs and the U.S. educational system. Tumblr founder and CEO David Karp (who himself skipped college in favor of entrepreneurship) will pose the questions during a live interview at 1:00 p.m. PT/4:00 p.m. ET.
