Marc Andreessen has been invited to join the board at eBay. The online auction company has been struggling of late, never mind CEO John Donahoe's assertion that what's bad for the American economy is good for eBay. Andreessen, probably smelling the stink blowing in from the rising tide, stockpiled enough venture capital to last Ning through a "nuclear winter." Proving his acumen at swindling investors if nothing else — and he does know how to keep employees overworked between stints at eager, young startups like Netscape and Ning and layoff-happy AOL.

After impressing almost no one for so, so long, Ning has relaunched and reclaimed the hearts and minds of techbloggers. Ning allows the free construction of Facebookesque social networks, customizable with a variety of content and content sources. Construction tools are dead easy, using a drag-and-drop layout similar to Typepad. Ning — largely funded by Netscape founder Marc Andreessen and cofounded by Web 2.0 hottie Gina Bianchini — is banking on the contextual ad market to support the site (though subscribers can sell their own ads by forking over a few bucks). Fortunately for nostalgia's sake, some of Ning's early triumphs remain intact — for example, Who Is a Bigger Douche.
