Ebay investiert zwei Millionen Dollar in Meetup.com

Ebay hat laut einer Mitteilung an die US-Börsenaufsicht zwei Millionen Dollar in das Social-Networking-Unternehmen Meetup.com investiert. Erst kürzlich wurde das Online-Auktionshaus in diesem Zusammenhang als Teil einer Investorengruppe genannt, die Höhe des Engagements war jedoch nicht bekannt.
Man habe die Informationen freiwillig bereitgestellt, da Ebay-Gründer Pierre Omidyar einen Anteil von mehr als zehn Prozent an Meetup.com hält. Es sei eine Frage guter Corporate Governance.

Meetup bietet ein Forum, in dem Nutzer ihre Interessen austauschen und dann Gruppen für reale Treffen bilden können. Der Dienst konkurriert mit entsprechenden Angeboten von Friendster und Orkut.
