GDS, the shoe show being held in Düsseldorf Sept. 10-12, is hitting the computer airwaves hard leading up to the exhibition. In addition to a blog sharing information of interest to those interested in fashion, shoes and the show itself (blog.gds-online.com/e), it has also established a presence on Facebook, Twitter, LinkedIn, YouTube and Hyves. About 780 exhibitors from 34 countries are expected to show 1,800 collections at the GDS this time. The total number of exhibitors is up by about 2 percent over last year's figure, and 3 percent higher than at the March event.
