LinkedIn Buys Rapportive

redletterdave writes "Business networking site LinkedIn acquired Rapportive on Wednesday, which is a Gmail add-on that provides information about your social contacts as you e-mail them. The deal was reportedly already in place by Dec. 8, but Rapportive confirmed the acquisition on Wednesday in its company blog. Rapportive, which is still available over Gmail, adds an e-mailer's social networking accounts, including their Facebook, LinkedIn and Twitter accounts, and overlays the information over open messages and e-mail drafts. Neither Rapportive nor LinkedIn would release the financial details of the acquisition, but sources close to the situation say the deal closed in the 'low teens' of millions of dollars."
