On Wednesday 16 January, you could have heard a pin drop at The Reference. That is quite unusual and in stark contrast with a normal workday at the office, when the atmosphere is usually buzzing. Why this sudden peace and quiet, you ask? Well, the first and for now only European Google Mobile Speed Hackathon was on! Over 50 Reffers took the train, metro, car or even skateboard and headed for the Google offices in Brussels. In the shadow of the European Parliament, they spent a full day working on the speed of our clients’ mobile websites. Our developers delved into the code to improve the actual speed. The UX-ers and analysts attended workshops in search of ways to improve users’ perceived speed.
