Following on from the success of Yahoo!’s internal Hack Days, I’m delighted to tell you that registration begins today for Yahoo!’s first-ever external Hack Day in Europe.

On June 16th and 17th, London’s historic Alexandra Palace will experience the buzz of innovation as up to 500 external web developers and new media technologists join together for a fun and free flowing exchange of ideas. The ultimate goal: to create and innovate the next generation of Internet services.
