Craig Newmark testified on Thursday that he regretted getting into bed with auction site eBay (EBAY) almost as soon as his head hit the pillow. The founder of Craigslist, the online classified site that has decimated large chunks of the newspaper industry, sold 28% of his company to eBay in August 2004. Within months, he recounted, eBay began to pull back on its promises, causing him to regret the decision.

During the negotiations more than five years ago, Meg Whitman, who was the CEO at the time, told Newmark that eBay would be happy to sit back as a minority shareholder for several years and use Craigslist as its exclusive venue for classified ads. Yet, shortly after the deal closed, eBay pushed for a bigger piece of the company and acquired an online classified company outside the United States. Both Whitman and company founder Pierre Omidyar testified that eBay was clear about its intentions.

The lawsuit, filed by eBay against Craigslist, involves the size of the former's minority stake in the privately held, relatively low-tech and highly popular classified site. eBay claims that Newmark diluted its share to 24% through a "self-dealing" scheme to issue more equity.

There's no doubt about it -- times are tough. People are struggling to find work and to pay the bills as the value of their homes and savings dwindle. The poor get poorer, and the rich get richer.

Or do they? It's all relative, of course, but world's billionaires have been taking some big hits too. We take a look at Sheldon Adelson, Kirk Kerkorian, and Lakshmi Mittal in their own separate posts, but here are some other billionaires who have lost billions this year (courtesy of Forbes and Business Sheet).

• Brothers Anil and Mukesh Ambani of India's private conglomerate Reliance lost $32.5 billion and $28.2 billion, respectively.
• Warren Buffett, the Sage of Omaha, lost $16.5 billion. Shares of Berkshire Hathaway Inc. (NYSE: BRK.A) are down about 32% since the beginning of the year.
• Microsoft (NYSE: MSFT) founders Bill Gates and Paul Allen lost $12.3 billion and $2.6 billion, respectively, while CEO Steve Balmer lost $6.5 billion. Shares of Microsoft are down 46% since the beginning of the year.
• Larry Page and Sergey Brin, cofounders of Google Inc. (NYSE: GOOG), lost $11.9 billion and $11.7 billion, respectively, and CEO Eric Schmidt lost $3.8 billion. The share price of Google has fallen 55% since the beginning of the year.
• Larry Ellison, CEO of Oracle Corp. (NASDAQ: ORCL), lost $8.2 billion. Shares of Oracle are down 21% since the beginning of the year.

This post is in response to a question from one of my loyal readers. Loyal enough to ask me a question, that is! It's so nice to know that there's someone reading my stuff besides me.

Her question is simply; What's eBay Inc.'s (NASDAQ:EBAY) plan C? She asked this in response to eBay's decision to change its China game plan from one of open competition to one of minority partner in a shared venture. I'm not sure what her vested interest in eBay is, but her question is valid nonetheless. Here's the problem -- I'm not sure eBay has a "plan C" nor am I certain whether or not it thinks it needs one. As of this writing, eBay auction stats are pretty much in keeping with the previous two years, although its after Christmas listing count bounce-back is progressing slower than '04 and '05. It will be a couple weeks before we can get a good picture as to the true condition of listing volume going into 2007.
