Having attended Macoun last year I will give the very first Objective-Cologne conference a try this year. Coming from Cologne myself I very much look forward to having an Objective-C/Cocoa conference right here in front of my door step.
I also immediately liked the international concept of the conference which led to a great “line-up” of speakers. Since in my eyes the developer community is a global one I found that a bit of a shortcoming of Macoun which is completely in German.
Oh, and of course I love the logo which includes a reference to Cologne’s historical landmark.
Ping me if you’re going and want to meet up.
