Heard on the Street: Three Fears for Facebook as IPO Approaches /WSJ - Rolfe Winkler: "If investors needed a reminder not to chase Facebook shares, they got three big ones over the past week. General Motors , major brand advertiser, plans to stop paying for Facebook ads. Some early investors will sell a lot more shares in the IPO than they previously planned. And the growing use of Facebook on mobile devices could, for the moment, eat away at the company's revenue."

Ad execs say jury still out on Facebook as medium /Reuters - Nicola Leske & Kate Holton: "...experts say Facebook has to step up its game in explaining how it can be useful and effective for companies to incorporate the site in their campaigns. "When I look at the GM news it is a little concerning," said Bernie Williams, a money manager for USAA. "They have to make that switch, from display to how to sell a product without ruining that social interaction. That could be a tough trick although they have 60 percent of the world's population."
