Confused by Wall Street? Join the club. Vinod Khosla, a venture capitalist who is one of Silicon Valley's most revered brains, doesn't get what's happening, either. "If I can't understand it, I suspect a lot of people can't," he told Beet.tv's Andy Plesser in this video interview. "In the name of economic efficiency by slicing and dicing risk, we're reducing transparency, which is not a healthy thing." I was with him that far. But then he concluded: "Venture capital will be a pretty good place when we return to reality and invest in things we understand and are real." That rules out most Web startup investments made in the past couple of years. Heck, Khosla believes in cost-effective ethanol.

Vinod Khosla's boutique VC firm Khosla Ventures has lead a $3 million investment round in ZocDoc, a startup which aims to make it easier to schedule doctor's appointments online. Managing the bureaucracies of the healthcare industry, with a nest of on- and off-network providers, HMOs and the like would make the ancient Greek civil servants of Byzantium blanch. Health revolutionaries from Steve Case to Google haven't exactly set the healthcare industry on fire, so good luck with that. Considering Khosla is struggling to convince his own son to eat vegetables, it's a good thing he tapped Khosla Ventures partner David Weiden to sit on the company's board.

CARLSBAD, CA — Who are those cool cats in sunglasses at D6? Why, it's Jim Breyer of Accel Partners, a board member at Facebook, lunching with Wendi Murdoch, wife of the News Corp. CEO and chairwoman of MySpace China. Also at the table: Martha Stewart, seen here to the left; Vinod Khosla of Khosla Ventures; and Anne Wojcicki of 23andMe.

Ordinarily, this would be good news: Vinod Khosla, the former Kleiner Perkins venture capitalist, and his wife Neeru Khosla, have donated $500,000 to Wikipedia's nonprofit parent, the Wikimedia Foundation. But founder Jimmy Wales's dalliances with other VCs — chiefly Roger McNamee and Marc Bodnick of Elevation Partners — have cast a shadow over every dollar the organization receives. Is this one of the $500,000 donations McNamee recently said he helped broker? And if so, what do he and Khosla expect to get in return? For starters, keep a close eye on Wikipedia's articles on ethanol, a major business interest of Khosla's. Wales, ordinarily Wikipedia's front man, makes no appearance in the press release, quoted below:

We were right: Wikipedia founder Jimmy Wales really did skip off to Richard Branson's Caribbean getaway in early March, even as a scandal unfolded over his governance of the world's most comprehensive list of gay animals. The powwow on Necker Island, which included Google's Larry Page, Tesla Motors chairman Elon Musk, former British prime minister Tony Blair, and VC Vinod Khosla, discussed global warming. Branson asked: "Is the world on fire?"

Serial entrepreneur and PayPal cofounder Max Levchin's widget maker Slide will take in a new round of funding, according to Boom Town. The deal, put together by New York-based Allen & Company, is said to propel Slide's value well past the $60 million to $80 million set just over a year ago.
