EBay plans to grow by thinking small as it prepares for life apart from PayPal. The company says it is focusing on getting more people, as well as small- to mid-size businesses, to buy and sell items on its popular online marketplace. The effort comes as it attempts to address investor concerns about how it will fare later this year after it spins off its PayPal payments division, which has long been eBay's fastest-growing segment. EBay's first-quarter earnings may have mitigated investors' concern somewhat. The results beat expectations and revenue, excluding the impact of the stronger dollar, grew in both segments. A stronger dollar cuts into revenue generated overseas when it's translated back into dollars.
