LinkedIn Corp., a developer of a social network for business professionals that lists famed entrepreneur/investor Reid Hoffman as chairman, and Fusion-io Inc., a provider of flash memory used to increase the efficiency of large data centers that boasts Apple Computer founder Stephen Wozniak as chief scientist, may not seem to have a lot in common. But some of the same factors are fueling growth in both companies and contributing to the success of their initial public offerings. "We're both driven by this society's use of large quantities of data," said Fusion-io CEO David Flynn in a video interview with The Deal magazine on the floor of the NYSE soon after he rang the opening bell Thursday. "You're seeing that with social networking -- just aggregating massive amounts of information about us and our friends and helping us to communicate better and faster."
