The Netscape founder and high-profile Silicon Valley venture capitalist returned to Twitter on Jan.1, 2014, after 982 days of silence. He’s since made up for lost time with passionate, rapid-fire, multi-tweet missives about everything from the future of news to what we’re misunderstanding about tech valuations. There is no subject too big or too small for Andreessen, and some of his best tweets come in his replies to his followers. —Callie Schweitzer
