Starting today, XING banners and plaquards will be appearing throughout heavily trafficked areas in Vienna, Austria, including this huge banner that adorns the Hilton Vienna Hotel currently under construction.  The theme of the campaign is “Who’s connecting with whom – 5 Million members maintain their business relationships on XING.”  If you’re in Vienna this month, you’ll see the ads in the subway stations, at the bus stations, and office complexes.
