Marc Andreessen has long been a busy man; he's worked at or invested in Netscape, AOL, Ning, Digg, and Twitter, for starters.  Now, Andreessen's interests seem to have turned towards boards of directors, as he joined Facebook's earlier this year and hopped aboard eBay's yesterday evening.

eBay is in less than great shape right now.  Three-month, one-year, and five-year views of its stock show losses of 24.95, 47.50, and 23.2 percent, respectively.  Meanwhile, Compete puts the site's number of unique visitors on a downward trajectory, and we all know how sellers have responded to recent policy changes.

So is Andreessen stepping onto a sinking ship?  We'll leave the issue for you to discuss.  But if that's the case, perhaps he's packing a crate full of pumps and caulk.

John Donahoe, eBay's CEO, said in a statement, "Marc is a true visionary whose experience will be invaluable to eBay.  We look forward to learning from Marc's insights and expertise as we drive further innovation on our platform, invest in growth opportunities and develop technology that will further benefit our customers, build powerful communities and enhance e-commerce."

Keep an eye out for more changes, then, and if they're of a "social" nature, you'll have a good idea of their origin.
