By Sarah McBride AUSTIN, Texas (Reuters) – Entrepreneur P.K. Fields was delighted when she won a contest and a chance to pitch her Los Angeles-based startup to a venture capitalist. So delighted, she dropped everything and flew 1,400 miles on her own dime to the South by Southwest Interactive conference in Austin, Texas, for just 20 minutes alone with angel investor Dave McClure as he was driven around town in a tiny red-and-black electric BMW i3. Fields is emblematic of the thousands of entrepreneurs who converge on Austin each year, hoping to rub shoulders with venture capitalists and win funding for their companies amid the current startup boom. But that convenience comes with a price: The growing volume of startups today at South by Southwest, or SXSW as many call it, engulfs both the startups and their audience.
