It goes without saying that neither company stands to directly benefit from a Facebook IPO. Renren is growing quickly, but struggling to produce material profitability. It toils away in China, where an already restrictive government can all but kill the site if it fears free-speaking masses. Quepasa's faring even worse. Revenue plunged 46% in its most recent quarter after a 32% decline in monthly active users of its namesake website. Would the market have been silly enough to bid up MySpace or Bebo over the past few days if they traded publicly as stand-alone social networking sites? It wasn't all crazy. Recent debutante Jive Software ( NAS: JIVE ) -- a provider of social networking software for companies -- has mostly marched in place over the past three days. White-collar social hobnobbing website LinkedIn ( NAS: LNKD ) did pop initially on the Facebook news, but it's right back to where it was last Thursday.
