As posted before, I spent the last week at LinuxTag in Berlin. For us (ownCloud) it was pretty good. It was our first appeareance there, hence we got a lot of interest and visitors. We got higher visibility through the two booths, i suppose, but especially because of our most recent ownCloud 4 release. All in all a good combination that made ownCloud overtake Ubuntu One in Google Trends (12 months view, click to enlarge).
During LinuxTag, Frank also gave an interview to Golem, a German online magazine, about features and the history of ownCloud and the company behind.
